TV Antenna Installation SA 2026 - Get Quotes
Reception problems in South Australia divide along a line most people can see from their own street, which is the Adelaide Hills escarpment. Across the plains, transmission from Mount Lofty arrives strong and direct, and a picture breaking up there usually points at the installation rather than the signal, most often a corroded connection, water in the cabling or an antenna that has been on the roof for twenty five years. In the Hills themselves and in the valleys behind them, terrain blocks and reflects the signal, which produces a different problem entirely. The important consequence is that the instinctive fix of a bigger antenna or an amplifier helps in one situation and actively makes the other worse, because an amplifier boosts interference and reflections alongside the signal you want. Working out which side of that line you are on is what decides whether the job is a two hundred dollar repair or a redesign.

At a Glance - What Your Symptom Points To
| Symptom | Likely Cause | Amplifier Helps | Usual Fix |
|---|---|---|---|
| All channels gone at once | Cable, connection or antenna failure | No | Diagnosis call out |
| Some channels pixelate | Marginal quality on one multiplex | Sometimes | Realign or replace antenna |
| Worse when it rains | Water in cable or connector | No, makes it worse | Reterminate and seal |
| Worse in the evening | Impulse noise from appliances | No | Find the interference source |
| Ghosting or intermittent lock | Multipath reflection | No, makes it worse | Reposition or directional antenna |
| One room only | Outlet, splitter or that cable run | No | Repair that leg |
Diagnosis Depth: Strength and Quality Are Not the Same Thing
Digital television has two separate measurements and confusing them is behind most of the money wasted on reception problems. Signal strength is how much of it arrives at the tuner. Signal quality, expressed as a bit error rate or a modulation error ratio, is how clean that signal is once it gets there. A picture needs both, and a strong dirty signal produces exactly the same pixelation as a weak clean one.
That distinction explains why amplifiers so often disappoint. An amplifier raises strength and does nothing for quality, so on a signal degraded by reflections, impulse noise or a corroded connection it amplifies the problem in step with the signal and can push the tuner into overload. Installers see amplifiers fitted by householders that made reception measurably worse, and removing one is occasionally the entire fix.
Digital also behaves differently from the analogue picture people remember. Analogue degraded gradually into snow, giving plenty of warning. Digital holds a perfect picture until the error rate crosses a threshold, then collapses into blocking and silence within a very narrow margin. A household that has never had trouble and suddenly loses channels has usually been sitting just above that threshold for years while a connection slowly corroded.
What Actually Causes Pixelation
Corroded connections are the most common fault an installer finds and the cheapest to fix. The plug at the wall outlet, the joint at the antenna and any junction in the roof space all oxidise over time, and a connection that has quietly degraded for a decade eventually crosses the threshold where the picture collapses. Water in the cabling is the second and it produces a distinctive symptom. Reception that is fine in dry weather and breaks up during or after rain almost always means moisture has entered a connector or a damaged section of cable, and the sheath allows water to travel some distance from the entry point. Conditions here make the effect more pronounced than in cooler states.
Old cable is a genuine cause in place of an upsell. Cable installed before digital transmission is frequently not adequately shielded for the task, and runs that were acceptable for analogue let in interference that digital tuners cannot tolerate. Installers take different positions on it. Adelaide installers vary on the detail more than you would expect. An installer working your suburb will know the pattern already.
Impulse noise from household equipment causes the evening problem people find baffling. Some LED lighting installed under lighting installation, certain motors, older dimmers and some solar inverters generate interference that travels into poorly shielded cable, which is why reception can fail reliably at the same hour each night. Splitters degrade a signal every time one is added. Each split halves the available signal, so a house with an original outlet plus three added over the years may be running four ways off an antenna designed for one, and the furthest room fails first. It is the detail most often left out of a phone description.
Antenna age matters more than owners expect. An antenna is exposed to sun, salt, wind and rain continuously, and elements corrode, brackets loosen and the reflector distorts, so a unit past twenty years is generally at the end of its life regardless of how it looks from the ground. Anything electrical alongside the work is covered at electrical services. Alignment drifts over time on a mast that has loosened. A strong wind, a storm or simple bracket fatigue can shift an antenna a few degrees, which is enough to lose a marginal channel while the rest continue working normally.
| Fault | Tell | Typical Fix Cost |
|---|---|---|
| Corroded connection | Gradual onset, then sudden loss | Call out only |
| Water in the cable | Worse in wet weather | Reterminate or replace run |
| Old unshielded cable | Interference, some channels | Recable that leg |
| Impulse noise | Same time each evening | Find the source first |
| Too many splitters | Furthest room fails first | Distribution amplifier |
| Antenna past its life | Twenty years plus, coastal | $280 - $650 replaced |
Adelaide Terrain and Why Location Decides Everything
Metropolitan transmission comes from the Mount Lofty Ranges, and across the Adelaide plains that arrangement works well. Suburbs from the coast through to the foothills generally have a clear line toward the transmission site, which is why most plains reception problems turn out to be installation faults rather than signal faults. The Hills themselves are a different environment despite being closer to the transmitter. Terrain blocks, valleys shadow, and a property in a gully behind a ridge can have noticeably worse reception than one twenty kilometres away on flat ground. Having it stated upfront is what avoids a second visit.
Multipath describes the specific Hills problem and it is not solved by more signal. Reflections off slopes and ridges arrive at the antenna fractionally after the direct signal, and the tuner receives overlapping copies that degrade quality regardless of how strong they are. The quote seldom spells it out unless you ask. It rarely appears on a quote unless somebody asks. On a coastal property the effect is stronger again.
A highly directional antenna is the usual answer to multipath. Rejecting signal arriving from other angles matters more than gathering more of it, which is a different design goal from the wideband antenna that suits a plains installation. Mast height is the other Hills variable and it is genuinely worth paying for. Lifting an antenna two or three metres can clear a ridge line or move it out of a reflection pattern, and that changes the result far more than a better antenna at the original height would. Looking at what the neighbours have installed is the cheapest survey available.
If the houses around you have tall masts, large directional antennas or dishes, that tells you what your property is likely to need before anybody quotes. Where terrestrial reception cannot be made to work, the satellite service designed for that situation is the alternative. It requires a dish and a decoder, costs more to install than an antenna and is the correct answer in genuinely shadowed locations. Any roof condition issues found while up there are covered at roof repairs. Householders rarely connect the two until it is explained.
| Location | Usual Signal Picture | What the Job Involves |
|---|---|---|
| Adelaide plains suburbs | Strong and direct | Usually a repair, not a redesign |
| Coastal suburbs | Good, hardware corrodes | Replacement on a cycle |
| Foothills | Generally fine | Standard installation |
| Hills valleys and gullies | Shadowed, multipath | Directional antenna, mast height |
| Behind a ridge line | Weak or reflected only | Height, or satellite |
| Regional and remote | Depends on local transmitter | Local knowledge matters |
The Amplifier That Made It Worse
Amplifiers are sold in hardware stores as a general fix for reception problems, and on a substantial share of South Australian properties they either achieve nothing or actively degrade the picture. The reason is straightforward once the strength and quality distinction is clear, since an amplifier increases everything arriving at its input including noise, reflections and interference, and the ratio between signal and everything else stays exactly where it was.
Two specific failures are common. On the Adelaide plains where signal from Mount Lofty is already strong, adding an amplifier can overload the tuner, which produces pixelation on a set that was working fine and looks identical to a weak signal problem. In the Hills where the issue is multipath reflection, an amplifier boosts the reflections alongside the direct signal and the error rate does not improve. Where an amplifier genuinely helps is a long cable run or a house split several ways, because there the signal is adequate at the antenna and losing level through distribution, and a masthead amplifier placed at the antenna over at the television is the correct arrangement. That position matters, since amplifying at the wall outlet boosts whatever noise the cable has already collected on the way down. If a household has fitted an amplifier and reception has not improved, removing it before paying for anything else is a free experiment worth running.
Amplifiers, Splitters and Distribution
Where amplification is genuinely needed, the masthead position at the antenna is the right arrangement. Boosting the signal before it travels down the cable means the cable losses apply to an already lifted signal instead of the other way round. A distribution amplifier suits a house feeding several outlets. Each split halves the available signal, so four outlets from one antenna quarter it, and a distribution amplifier restores the level to each leg. Two quotes will often diverge on exactly this point.
Indoor boosters plugged in behind the television are the least effective option and the one householders buy most. By that point the signal has already travelled the full cable run and collected whatever interference it was going to collect. Worth settling before anyone climbs the roof. Few householders think to raise it when booking. Worth raising even if it seems minor at the time.
Gain needs matching to the situation rather than maximised. An amplifier with more gain than the installation requires pushes the tuner toward overload, and installers select gain against a measurement in preference to picking the largest number available. Power supply is a failure point people forget about. Masthead amplifiers, commonly Kingray or Matchmaster units, are powered through the coaxial cable from a unit inside, and that power supply failing produces a total loss of picture that looks like an antenna fault. Giving that context lets an installer price the job accurately.
Removing an unnecessary amplifier is occasionally the whole repair. Where a household has added one to a strong signal area, taking it out restores the picture at no cost beyond the call out. Adding a power outlet for the supply unit is covered at powerpoint and light switch installation. Installers differ on this more than the call out fee suggests. A single question when booking usually settles which applies.
Antennas, Masts, Cabling and Outlets
Antenna choice follows the signal environment rather than a price tier. A wideband antenna suits a strong plains signal, while a high gain directional unit, from a maker such as Matchmaster or Hills Antenna, is what a shadowed or reflection prone Adelaide Hills location needs, and fitting the wrong one produces a poor result at either price. Mounting hardware fails before the antenna does on many properties. Brackets, U bolts, mast clamps and the mast itself all corrode, and a unit that appears fine from the ground can be held on by fasteners that have lost most of their section. Most will volunteer it once you ask the question.
Network cabling follows similar rules, covered at data and communications cabling. Cable specification matters more under digital than it did under analogue. Quad shield coaxial such as RG6 rated for the application resists the interference that older cable admits, and Australian Standard AS 1367 covers the installation of receiving systems, and recabling a single run is frequently cheaper than chasing an intermittent fault through the old one. The answer changes what the visit actually costs. Local conditions sharpen that effect compared with cooler states.
Cable routing affects both performance and longevity. Camera cabling has the same constraints, covered at CCTV installation. Runs that sit against metal, share a conduit with power cabling or pass through a roof space reaching well over fifty degrees in an Adelaide summer all degrade faster and perform worse. Wall outlets are a common weak point and cheap to renew. The terminations behind a plate loosen and oxidise, and a plate that has been removed and refitted several times over a house's life is a likely candidate on an intermittent fault.
Additional outlets at $120 to $250 depend almost entirely on the cable run. A room adjacent to an existing outlet with roof space access above is straightforward, while a run to the far end of a single storey house with a low pitched roof is considerably more work. Other work needing roof space access is covered at ceiling fan installation. A full recable at $450 to $1,200 makes sense on an older property with several failing legs. Replacing one run at a time on a house with original cabling throughout usually costs more in the end than doing it once properly.
| Component | Typical Life | Fails As |
|---|---|---|
| Antenna, inland | 20 to 25 years | Gradual loss of marginal channels |
| Antenna, coastal | 10 to 15 years | Corroded elements and fittings |
| Mast and brackets | Varies with exposure | Movement, then alignment loss |
| Coaxial cable | 15 to 25 years | Water entry, shield degradation |
| Wall outlet | Long, but disturbed often | Loose or oxidised termination |
| Masthead amplifier | 10 to 15 years | Total loss, looks like antenna |
The Coastal Strip and Why Hardware Dies First There
An antenna on a roof at Semaphore, Grange, Henley, Glenelg or Brighton lives in a materially harsher environment than the same antenna at Mitcham or Golden Grove, and the difference shows in service life instead of in reception. Salt carried in marine air settles on every exposed surface and accelerates corrosion on the aluminium elements, the steel mast, the bracket fixings and critically on the coaxial connector at the antenna head, which is the single most common failure point on the metropolitan beaches. Where an inland antenna might run twenty five years, a coastal one is frequently at the end of its useful life at ten to fifteen. Two things are worth specifying rather than accepting the standard offering when you live near the water. Stainless steel fixings and brackets cost slightly more and last several times longer than galvanised, and the difference is most of the reason one installation outlasts another on the same street. And the connection at the antenna should be properly weatherproofed with self amalgamating tape and not left as a taped joint, since that connector is where salt air and moisture do their work. Prevailing westerlies carry salt well beyond the first row of houses, so a property four hundred metres back is in a meaningfully different environment from one four kilometres inland even though neither has a sea view. Solar and roof hardware faces the same exposure, covered at solar panel installation.
Adelaide Roofs, Tiles and Why This Is Not a DIY Job
The temptation to save a call out fee by going up yourself is understandable and it is the wrong economy on most South Australian houses. Falls from residential roofs cause serious injuries every year and the roof is where every antenna fault ultimately sits. Adelaide housing presents three specific hazards. Older terracotta and concrete tiles on inner suburb cottages and villas become brittle with age and crack under weight, and a cracked tile that nobody notices becomes a leak that shows up in a ceiling months later. Metal roofing reaches temperatures in an Adelaide summer that make it both dangerous to touch and genuinely slippery underfoot, and the pitch on many post war homes is steeper than it appears from the ground. And a mast that has loosened is unstable to work against, which is precisely the situation somebody investigating an alignment problem walks into. A professional carries harness equipment, knows how to distribute weight across tile battens and is insured for both the property and themselves. The practical middle ground is to do the free checks from inside the house, which covers retuning, testing other televisions, swapping leads and removing any amplifier, and to leave anything above the gutter line to somebody who does it daily. Roof condition work sits at roof repairs.
Weather, Storms and Seasonal Failures
Antenna faults cluster after storms and the reason is mechanical rather than electrical. Strong winds move a mast that has loosened, shift alignment by a few degrees and occasionally bring an antenna down entirely, which is why installers see a surge of calls following a front. Reception that degrades through a wet period usually means water ingress. A connector that was marginally sealed admits moisture over successive days, and the fault may persist for a week after the rain stops as the cable dries out.
Adelaide roof space temperatures are genuinely extreme in summer and shorten the life of everything in there. Cable, splitters and amplifier power supplies all sit in a space that regularly exceeds fifty degrees, and components fail there sooner than their rated life suggests. It shows up on the final invoice otherwise. The question weighs considerably more on an older property.
Tree growth is a slow cause that people rarely connect to the symptom. Foliage between the antenna and the transmitter absorbs signal, and a problem that has worsened over several years without any storm or fault may simply be a tree that has grown. Atmospheric conditions cause occasional interference that is nobody's fault. Temperature inversions can allow distant transmitters to interfere with local ones, producing reception problems that appear for a day or two and resolve without intervention. Clearing foliage and debris around the roof is covered at gutter cleaning.
Retuning, Channel Changes and the Fault That Is Not a Fault
Broadcasters periodically change transmission parameters, restack frequencies or adjust which multiplex carries which channel, and a television holding old settings loses channels for a reason no installer can find on the roof. Retuning is free, takes a few minutes and resolves a meaningful share of the calls installers attend.
The process differs slightly between brands and is worth doing properly as against half way. A full retune, sometimes called a factory or first time installation scan, clears the stored channel list and rebuilds it, whereas an update scan adds new services without removing stale entries and can leave a set switching to a frequency that no longer carries anything. Where a household has several televisions plus a recorder or a set top box, each needs retuning separately, which is why one set works and another does not after a change. Two situations look like a fault and are not. A channel that has moved position in the list is simply where the broadcaster now puts it. And a set that finds duplicate copies of the same channel is receiving from two transmitters, which on the Adelaide fringe and in parts of the Hills is normal, and deleting the weaker set of duplicates is the fix rather than calling anybody.
Licensing, Roof Safety and Who Should Do This
Cabling work connecting to a telecommunications network requires a registered cabler, which is a specific registration not simply a general trade licence. Television antenna cabling that is purely internal falls in a different category from work touching the network, and a competent installer will explain which applies. Any work involving electrical connection requires a licensed electrician. Fault tracing across a property sits at electrical fault finding.
A masthead amplifier power supply plugging into an existing outlet is one thing, while a new outlet or any work at the switchboard is licensed electrical work. Working at height carries the real risk in this trade, which is most of the argument for paying somebody who does it daily. Adelaide roofs include steep pitches, brittle older tiles and metal sheeting that becomes dangerously hot and slippery in summer, and falls from residential roofs cause serious injuries every year. That is worth settling before anybody climbs onto the roof.
Tile damage is the common collateral cost of a roof visit. Aged terracotta and concrete roof tiles crack under foot, and an installer who notes and replaces a broken tile is doing the job properly rather than creating a leak for somebody else to find. Insurance is worth confirming before anybody climbs. Periodic checks of the wider installation sit at electrical safety inspections.
Public liability covers damage to the property and the installer's own cover matters if they are injured, and workplace duties sit with SafeWork SA. On a rental property antenna and reception issues are ordinarily the landlord's responsibility, since the installation is part of the premises. Tenants should report reception faults in writing, and disputes have a pathway through SACAT. That one detail can reshape what an installer recommends.
| Work | Who Can Do It | Ask For |
|---|---|---|
| Antenna supply and mount | Antenna installer | Insurance and roof experience |
| Coaxial cabling and outlets | Registered cabler where required | Registration details |
| New power outlet | Licensed electrician | Licence number |
| Switchboard work | Licensed electrician | Certificate of compliance |
| Roof access | Anyone competent and insured | Public liability cover |
| Tile replacement after damage | Installer or roofer | Who carries that cost |
Units, Strata and Shared Antenna Systems
Reception problems in an Adelaide unit or apartment behave differently from a house, because the antenna and the distribution system are almost always common property in place of yours. A single antenna on the roof feeds every unit through a distribution amplifier and a network of splitters and cabling, and a fault anywhere in that chain affects multiple residents.
That changes what you should do first. Before paying anybody, ask neighbours whether they have the same problem, because a shared fault is a corporate matter and an individual owner arranging repairs on common property generally cannot recover the cost. Where only your unit is affected, the fault is likely in the cabling within your lot or at your own outlet, which is yours to fix. Older Adelaide unit blocks frequently run original cabling and a distribution system installed for analogue transmission, which performs poorly under digital, and the sensible remedy is a building wide upgrade rather than a succession of individual repairs that never quite resolve it. A corporation facing repeated complaints across several units is usually better off replacing the head end and the distribution than paying for call outs. Report problems to the corporation in writing, and where several owners are affected, raising it collectively carries considerably more weight than individual complaints do.
Where South Australian Television Actually Comes From
Understanding the transmission picture explains most of what an installer will tell you about your property. Metropolitan Adelaide is served principally from the Mount Lofty Ranges, which sits east of the city at elevation, and that single location covers the plains from the northern suburbs through to the southern beaches with a generally strong signal. Because the transmission point is elevated and to the east, antennas across the plains point broadly in the same direction, which is why a row of houses on a suburban street usually has antennas aligned the same way and why one pointing differently is worth a second look. The Hills are closer to the transmitter and receive worse, which surprises people until the terrain is considered, since being close to an elevated source does not help if a ridge sits between you and it. Regional South Australia is served by a network of transmitters covering the major centres and their surrounds, with self help and retransmission arrangements filling gaps in some districts. Properties sitting between coverage areas are the difficult cases, and they are where a high mast, a highly directional antenna or the satellite service designed for exactly that situation become the realistic options over a better antenna at the existing height.
Regional Reception Across South Australia
Metropolitan Adelaide is served from the Mount Lofty Ranges and reception across the plains is generally reliable. Most problems in the suburbs are installation faults rather than signal faults, which is why a diagnosis call out frequently resolves them without new hardware. The Adelaide Hills needs local knowledge more than any other part of the state. Terrain varies street by street, and an installer who works the area regularly knows which valleys are difficult and what has worked on comparable properties.
Regional centres including Mount Gambier, Port Lincoln, Whyalla, Port Pirie and the Riverland towns are served by their own transmission arrangements. Reception is generally sound near those centres and degrades with distance and terrain in the usual way. Few householders raise it in advance. A installer who asks about it is diagnosing properly.
Rural properties between transmission areas face the hardest problems. High masts, highly directional antennas and in some cases the satellite service are the realistic options, and a local installer will know which applies before attending. Coastal regional towns on the Fleurieu, Yorke and Eyre Peninsulas combine marine corrosion with variable terrain. Hardware specification matters as much there as in the metropolitan coastal suburbs.
| Area | Typical Situation | What It Usually Needs |
|---|---|---|
| Adelaide plains | Strong direct signal | Repair, not redesign |
| Metropolitan coast | Good signal, corrosion | Stainless fittings, sealed joints |
| Adelaide Hills | Shadowing and multipath | Directional antenna, height |
| Regional centres | Local transmission | Standard installation |
| Rural between areas | Marginal or none | High mast or satellite |
| Coastal regional towns | Corrosion plus terrain | Specification matters |
| Ask Every Installer | Why It Matters | A Good Answer |
|---|---|---|
| Will you measure before quoting | Separates diagnosis from selling | Yes, level and quality both |
| Is the call out credited | Common on a resulting job | Yes, stated upfront |
| Stainless fittings near the coast | Doubles hardware life | Offered without prompting |
| Who pays for a broken tile | Roof access damages tiles | Agreed before they climb |
| What warranty applies | Parts and labour differ | Both stated in writing |
| Public liability insurance | Work at height on your roof | Confirmed on request |
| Check | Takes | What It Rules Out |
|---|---|---|
| Retune the television | Five minutes | Broadcaster parameter change |
| Test another television | Two minutes | That set or that outlet |
| Swap the aerial lead | One minute | A failed lead, a common fault |
| Unplug any booster | One minute | Overload on a strong signal |
| Note when it happens | Over a few days | Narrows the diagnosis sharply |
| Ask a neighbour | A conversation | A shared or area wide problem |
Five Free Checks Before You Book Anybody
A reasonable proportion of reception call outs turn out to be something the householder could have resolved, and running through a short list first costs nothing but ten minutes. None of it involves going on the roof, which is the part worth paying somebody else to do.
Retune the television first, since broadcasters occasionally change transmission parameters and a set holding old settings loses channels for a reason nothing physical explains. Check whether the problem appears on every television in the house or only one, because a single affected set points at that outlet, that cable or that tuner in preference to at the antenna. Swap the lead between the wall and the television for a known good one, as those leads fail more often than anything on the roof. Unplug any amplifier or booster that has been added and see whether reception improves, which on a strong signal area it sometimes does. And note precisely when the problem occurs, whether that is during rain, at a particular hour, or constantly, because that pattern is the single most useful thing you can tell an installer and it frequently shortens the diagnosis substantially. Consumer guarantees on the work itself come from the ACCC, with contractor obligations through Consumer and Business Services.
What Antenna Work Costs
A diagnosis call out runs $120 to $220 and is the right starting point where the cause is unclear. Many installers credit that fee against the resulting work, which is worth confirming when booking rather than assuming. A new antenna supplied and installed lands between $280 and $650. The range reflects antenna specification, roof height and pitch, whether a new mast is needed and how much cabling is replaced at the same time.
Replacing an antenna on an existing sound mount is cheaper at $220 to $420. Where the mast, brackets and cabling are all serviceable, only the antenna and its connection need renewing. On an older property it matters more. This is often what separates one quote from another.
Additional wall outlets at $120 to $250 depend on the cable run instead of the outlet. A room adjacent to existing cabling with roof access above is straightforward, while a long run through a low pitched roof is not. Fitting a masthead amplifier runs $180 to $350 including the power supply. It is worth having only where a measurement supports it, and fitting one to a strong signal can make reception worse.
A full recable at $450 to $1,200 suits an older property with failing cabling throughout. Doing it once is generally cheaper than replacing individual runs as each one fails. That detail can reshape the recommendation. Operators who work the area know it without being told.
What to Look Out For
Be cautious about a quote for a new antenna given before anything is measured. Most metropolitan reception problems are cabling, connection or amplifier faults, and replacing the antenna on a plains property without diagnosis frequently changes nothing. Question an amplifier recommended without a measurement. On a strong Adelaide plains signal an amplifier can overload the tuner, and on a Hills multipath problem it boosts the reflections alongside the signal. Ask for stainless fittings if you live near the water. Galvanised hardware on a coastal roof corrodes in a fraction of the time, and the cost difference is small against a premature replacement.
Agree who carries the cost of a cracked tile before anybody goes up. brittle terracotta and concrete tiles break under foot, and an unresolved broken tile becomes a roof leak. Confirm licensing for any electrical component of the work. A registered cabler handles the cabling where required and a licensed electrician handles anything electrical, and business obligations can be checked through the South Australian government.
How to Get Useful Quotes
Name your suburb rather than describing the area. Reception varies enormously between the plains, the foothills and the Hills valleys, and an installer who works your area will know what to expect before attending. Describe exactly which channels fail and when. All channels, some channels, one room, during rain or at a particular hour each evening are five different diagnoses, and that detail shortens the visit considerably. Say how old the antenna and the house are. A twenty five year old antenna on original cabling is a different proposition from a five year old installation with an intermittent fault.
Mention the roof type and storeys. Tile or metal, single or double storey and the pitch all affect access, and they are the details that change a quote once somebody arrives. Note any amplifier or booster already fitted. It may be the cause, and removing it is a free test worth running before anybody quotes for hardware. Have each quote state whether measurement is included, what the call out covers, the hardware specification, the warranty on parts and labour and who carries tile damage. Pin down those five and the quotes become comparable, and mounting a television afterwards is covered at handyman services.

TV Antenna Installation FAQs - SA 2026
Why does my picture pixelate?
Digital television needs both signal strength and signal quality, and pixelation means quality has crossed a threshold. Common causes are a corroded connection, water in the cabling, old unshielded cable, interference from household equipment, or too many splitters. On the Adelaide plains it is usually the installation rather than the signal, since transmission from Mount Lofty arrives strong.
Will an amplifier fix it?
Often not, and sometimes it makes things worse. An amplifier raises strength and does nothing for quality, so it boosts noise and reflections alongside the signal. On a strong plains signal it can overload the tuner. In the Hills it amplifies multipath reflections. If you have already fitted one, removing it is a free test worth running first.
Why is reception worse in the Adelaide Hills than on the plains?
Terrain. The plains have a clear path to the Mount Lofty transmission site, while Hills valleys and gullies are shadowed by ridges and suffer multipath, where reflections arrive fractionally after the direct signal and degrade quality. The answer is a highly directional antenna and mast height rather than more signal.
My reception only breaks up when it rains. Why?
Water has entered a connector or a damaged section of cable. The coaxial sheath lets moisture travel some distance from the entry point, and the fault can persist for days after the rain stops while the cable dries. The fix is reterminating and properly sealing the joint, usually with self amalgamating tape at the antenna head.
It fails at the same time every evening. What causes that?
Impulse noise from household equipment. Some LED lighting, certain motors, older dimmers and some solar inverters generate interference that couples into poorly shielded cable. The pattern of failing reliably at one hour is the clue. Finding and addressing the source matters more than changing anything on the roof.
How long does an antenna last?
Twenty to twenty five years inland, but only ten to fifteen on the metropolitan coast. Salt in marine air corrodes the aluminium elements, the mast, the bracket fixings and especially the connector at the antenna head. Specifying stainless steel fittings near the water costs slightly more and lasts several times longer.
Should I replace the antenna or repair the cabling?
Measure first. A quote for a new antenna given before anything is measured is selling rather than diagnosing, and most metropolitan problems turn out to be cabling, connections or an amplifier. A diagnosis call out at $120 to $220 is the right starting point, and many installers credit it against the resulting work.
What does a new antenna cost installed?
$280 to $650 supplied and fitted, depending on antenna specification, roof height and pitch, whether a new mast is needed and how much cabling is replaced. Replacing an antenna on an existing sound mount is cheaper at $220 to $420. A full recable on an older property runs $450 to $1,200.
I live in a unit and my reception is bad. Who fixes it?
Check with neighbours first. The antenna and distribution system in an Adelaide unit block are almost always common property, so a shared fault is a corporate matter and arranging repairs privately generally means you cannot recover the cost. If only your unit is affected, the fault is likely in your own cabling or outlet.
What should I check before calling anyone?
Retune the television, since broadcasters occasionally change parameters. Check whether every set is affected or only one. Swap the lead between wall and television, as those fail often. Unplug any booster that has been added. And note exactly when the problem happens, because that pattern is the most useful thing you can tell an installer.

How The Quote Yard Works
We connect you with independent local tradies and service providers, we don't perform any trade work ourselves. Tradies provide their own quotes directly to you. Always confirm licensing, insurance, and scope of work before engaging any provider.
All SA tradies are required to hold appropriate licences. Verify at Consumer and Business Services SA.
Figures on this page are indicative 2026 SA estimates only and vary with roof type and height, antenna specification, cabling runs, the number of outlets and whether an amplifier or a mast is required. Quotes should always be obtained for your specific property. Electrical licensing, cabling registration, work health and safety and consumer protection requirements are set by legislation and are periodically updated, so confirm the current position with the relevant authority and your installer before relying on any figure.
