Yes. Active Audio & TV is fully licensed and insured for residential and commercial audio visual work across Queensland and New South Wales.

Craig has over 40 years of experience installing TV antennas, MATV systems and commercial audio across the Gold Coast and Central Coast.

Most Gold Coast suburbs receive free-to-air TV from the Mount Tamborine transmitter site (Springbrook area), with additional fill-in sites at locations such as Nerang and Tallebudgera to cover shadowed areas. Coastal and hinterland suburbs may pick up different sites depending on line-of-sight, which is why antenna type and aim matter.

Craig tests on-site with a field-strength meter to confirm which transmitter your property should be aligned to — guessing or copying the neighbour's setup often leads to ongoing reception problems.

Central Coast reception typically comes from the Bouddi transmitter (serving Terrigal, Woy Woy, Gosford and surrounding areas) and, in some western and hinterland pockets, from Katoomba or other Blue Mountains sites. Peninsula suburbs such as St Huberts Island, Empire Bay and Kincumber can have different signal paths to suburbs inland at Wyong or Tuggerah.

Coastal salt exposure and tree cover are common issues on the Central Coast. A site survey identifies the correct transmitter, antenna gain and amplifier strategy for your address.

VHF (Very High Frequency) and UHF (Ultra High Frequency) are different parts of the radio spectrum used for TV broadcasting. Some channels are VHF (lower frequencies, longer wavelength) and others are UHF (higher frequencies, shorter wavelength).

Your antenna must be designed to receive the bands used by your local transmitters. A UHF-only antenna will miss VHF channels; a VHF-only antenna will miss UHF channels. On the Gold Coast and Central Coast, a quality VHF/UHF combination antenna is usually the right starting point, but high-gain yagi or phased-array models are chosen after signal testing.

Signal strength is how much RF power arrives at your TV or meter — think of it as volume. Signal quality (often called MER or BER on professional meters) measures how clean and error-free that signal is.

You can have strong but unusable TV if the signal is distorted by interference, reflections or overdriving an amplifier. Conversely, a modest signal that is clean will often give a perfect picture. Professional diagnosis checks both — not just whether a booster makes the strength number go up.

A total loss of signal usually points to a hard failure somewhere in the chain:

• Antenna cable unplugged or broken internally
• Lightning or power surge damage to amplifier or tuner
• Snapped antenna element or bent boom after a storm
• Failed wall plate or splitter
• Power supply unplugged on a masthead amplifier (common in ceilings)

Check that the antenna cable is firmly screwed into the TV (not an HDMI port) and that any amplifier power supply is plugged in. If one TV works and another does not, compare inputs and cables before assuming the roof antenna has failed.

Rain fade on free-to-air TV is not normal for a healthy system. Occasional heavy rain should not wipe out digital channels. If yours does, typical causes are:

• Water ingress at a connector, splitter or wall plate
• Cracked coax cable sheath letting moisture into the copper
• Corrosion at the antenna balun or F-connector on the roof
• Marginal signal that only just works in dry weather

Water in the cable is the most common culprit on the coast. The connection looks fine from the outside but resistance jumps when wet. Craig pressure-tests and replaces affected fittings and cable runs.

Intermittent reception is frustrating because it suggests a loose or failing connection rather than a permanently broken antenna. Look for:

• Loose F-connector at the TV, wall plate or splitter
• Wind moving a marginal antenna on a tall mast
• Thermal expansion opening a cracked solder joint on the roof
• Failing amplifier that overheats and cuts out
• Tree branches swaying into the signal path
• Interference from appliances that cycle on and off (pool pumps, solar inverters, LED drivers)

Note when it happens — time of day, weather, which TV — and mention it when you call. That detail often points straight to the cause.

Channels are broadcast on different frequencies from the same or different transmitters. If only some channels fail, causes include:

• Band-specific antenna fault — VHF elements damaged but UHF fine, or vice versa
• Amplifier overload — strong nearby channels swamp weaker ones
• LTE interference — often wipes out a specific UHF block
• Wrong transmitter — antenna aimed at a fill-in site missing main-network channels
• Out-of-date channel list — TV tuned to old channel numbers after a retune event

Run an automatic channel scan on your TV. If missing channels are consistent across all TVs in the house, the antenna system needs attention. If only one TV is affected, suspect that TV's tuner or its cable run.

Yes — whenever channels move frequency, you add a new TV, or after major work on the antenna system. Broadcasters occasionally change channel allocations; a retune finds the new locations.

How to retune (most Smart TVs):

1. Open Settings → Channel / Tuning / Antenna
2. Select Digital or Antenna (not Cable)
3. Run Auto Scan or Auto Tuning
4. Wait for the scan to finish — do not skip it partway through

If a retune does not restore channels that neighbours receive, the problem is not the TV memory — it is the antenna, cable or amplifier. See our guide on digital TV reception problems for more detail.

Yes. Each TV and splitter port steals signal. Connecting four TVs to one antenna without a designed distribution network typically loses 6–10 dB or more — enough to push a marginal installation into pixelation.

The fix is not always a bigger booster. You need the right combination of masthead amplifier (at the antenna) and distribution amplifier (before the splitter), sized for the number of outlets and cable lengths. Craig designs split networks so every outlet gets adequate signal without over-amplifying and causing interference.

A masthead amplifier mounts near the antenna on the roof or in the ceiling immediately below. It boosts the signal before cable losses stack up on the long run down to your living room. It requires a power supply (often plugged in behind a TV) that sends 14–18 V up the coax to power it.

A distribution amplifier sits before a splitter, boosting signal to feed multiple TVs. Using only a distribution amp without a masthead amp on long cable runs is a common DIY mistake — you amplify noise and losses that have already degraded the signal.

Some situations need neither; others need both. Incorrect amplifier choice is one of the most frequent causes of "I added a booster and it got worse."

Absolutely. Over-amplification clips and distorts the signal, causing pixelation on strong channels while weak ones still fail. Cheap boosters from hardware stores often have no filtering, no gain adjustment and the wrong gain level for your situation.

Other booster mistakes include:

• Installing a distribution amp when you only have one TV (unnecessary)
• Stacking multiple boosters in series
• Powering a masthead amp with the wrong voltage supply
• Amplifying a system that already has strong signal from a nearby transmitter

Craig measures signal before recommending any amplification — sometimes removing a misinstalled booster fixes the problem entirely.

Mobile phone towers transmit on frequencies close to some UHF TV channels. When LTE energy enters your antenna and cable, it can overload amplifiers and tuners, causing pixelation or complete loss of specific channels — often Channels 9, 10 or SBS in affected areas.

Fixes include:

• LTE band-pass filters installed before the amplifier
• Replacing overloaded wideband amplifiers with filtered models
• Correct antenna and amplifier gain — not just "more signal"

This is increasingly common across the Gold Coast and Central Coast as mobile networks expand. It is one of the first things Craig checks when channels suddenly disappear without physical damage to the antenna.

Yes. Electrical noise from poorly shielded LED globes and dimmers, solar inverters, pool chlorinators, electric fences and faulty power supplies can enter your TV via the antenna cable or mains wiring.

Clues that interference is electrical rather than antenna-related:

• Pixelation only when a specific device is running
• Problems at the same time each day (e.g. pool pump timer)
• One TV affected when a light switch is turned on

Try switching off suspect circuits at the board. If reception clears, an electrician may need to address the appliance. Craig can also install filtering and ensure your antenna cabling is properly earthed and shielded.

TV signals need a clear path from transmitter to antenna. Large trees — especially when wet — absorb and scatter signal. A new high-rise, neighbour's extension or crane can create a shadow zone that did not exist when your antenna was installed years ago.

Options include:

• Raising the antenna on a taller mast above the obstruction
• Relocating the antenna to a different roof plane with clearer line-of-sight
• Switching to a higher-gain directional antenna aimed at an alternative transmitter
• VAST satellite TV for properties in permanent terrain shadow

Craig assesses whether the obstruction is seasonal (deciduous trees) or permanent before recommending a solution.

Gold Coast and Central Coast properties face accelerated corrosion. Salt mist attacks aluminium elements, steel masts, baluns, F-connectors and amplifier housings. Within 5–10 years a budget antenna near the beach can look intact but perform poorly due to invisible corrosion at the balun or connector.

Craig uses marine-grade hardware, sealed connections, quality copper-centre coax and corrosion-resistant fittings. Periodic inspection is worthwhile — especially after storm season — to catch rust before it causes a sudden total failure.

If the main living-room TV is fine but a bedroom TV pixelates or shows no signal, the roof antenna is probably OK and the fault is in the internal distribution:

• Faulty wall plate or loose connector in the bedroom
• Splitters in the ceiling — one output failed
• Separate cable run damaged during renovation
• Bedroom TV set to Cable instead of Antenna input
• Extra booster behind one TV causing mismatch

Swap the TVs between rooms. If the problem follows the TV, it is the set. If it stays in the room, it is the cabling or outlet. In apartments, the building MATV network may need balancing — see our MATV systems page.

Yes, but it is less common than antenna faults. Signs the TV tuner is the issue:

• Antenna cable works on another TV but not this one
• All inputs fail including different antenna ports
• Problems started after a lightning storm (surge through antenna input)
• Very old TV with an analog-only tuner (rare now)

Test with a cheap set-top box or another TV on the same wall plate. If the spare device receives perfectly, your antenna system is fine and the TV needs repair or replacement. Craig can confirm this on-site so you do not pay for an unnecessary roof call-out.

Storms cause some of the most common emergency call-outs. Damage includes:

• Antenna bent, displaced or blown off the mast
• Mast fixings pulled through roof tiles or metal sheeting
• Lightning surge through coax destroying amplifier and TV tuner inputs
• Tree branches striking the antenna array
• Water forced into connectors and ceiling spaces

After severe weather, check the antenna from the ground for obvious movement. Do not climb the roof yourself. If multiple TVs and amplifiers failed at once, mention a possible lightning strike — surge damage can cascade through the whole system.

Replace the antenna when:

• Elements are bent, missing or heavily corroded
• The balun housing is cracked or green with corrosion
• Mast is rusted through at the roof mount
• Extensive repairs are poor value compared with a new installation
• Antenna is 15+ years old and performance is declining

Birds nesting in a log-periodic antenna can detune elements. Wasps and spiders in F-connectors cause intermittent faults. Sometimes a realignment and connector service restores performance; Craig will tell you honestly if replacement is the better value.

For most Gold Coast and Central Coast homes, no. Indoor and set-top rabbit-ear antennas lack the gain and height to reliably receive weak or reflected signals from Mount Tamborine or Bouddi transmitters. They work in rare situations — a high apartment facing the transmitter with a clear window — but are a common source of pixelation complaints.

A properly mounted outdoor antenna, sized for your location, will always outperform an indoor alternative. If body corporate rules restrict roof mounting, Craig can advise on discrete mounting options or MATV connection in apartment buildings.

Retail boosters are generic. They cannot correct a misaligned antenna, replace corroded cable, filter LTE interference or fix a broken balun. Common outcomes:

• Wrong gain — too much or too little for your signal level
• No LTE filtering — amplifies interference along with TV signal
• Installed in the wrong place — behind the TV instead of at the antenna
• Underlying fault ignored — water in the cable or a bent element

Professional installation avoids repeated DIY attempts and includes correct equipment, mounting, cabling and a signal guarantee — at very competitive rates.

VAST (Viewer Access Satellite Television) delivers free-to-air digital TV via satellite for homes that cannot get adequate terrestrial reception — common in hinterland, valley and heavily shadowed coastal pockets west of the highway.

You may need VAST if:

• Professional testing shows insufficient signal from all nearby transmitters
• Terrain or dense tree cover permanently blocks line-of-sight
• You are on acreage around Mudgeeraba, Tallai, Somersby or similar areas

Craig installs VAST satellite dishes, authorised set-top boxes and cabling. You must register for a VAST access card through the official process. See our satellite installation service for details.

A Foxtel dish itself does not receive terrestrial TV and should not block your antenna unless it is physically in the line-of-sight path. Problems arise when:

• FOXTEL and FTA share one cable without proper diplexing
• An old MATV head-end mixes satellite and antenna incorrectly
• Installer used the wrong wall plate (satellite vs TV port swapped)
• A dish mount disturbs the antenna mast

If FTA worked before a Foxtel or Starlink install and stopped after, the integration wiring is the first place to check. Craig separates or combines services correctly using diplexers and labelled outlets.

Starlink and NBN modems do not transmit on TV frequencies and will not interfere with your antenna in normal operation. Issues occur when:

• New cabling is run poorly alongside antenna coax, picking up electrical noise
• Starlink mount installation disturbs existing roof antenna fixings
• Shared roof space creates physical obstruction

Craig installs Starlink and TV antennas together with separated cable routes and proper mounting. NBN HFC or phone-line issues do not affect free-to-air TV — if both fail, suspect separate causes or a whole-house electrical event.

Multipath happens when the same TV signal reaches your antenna by two paths — directly from the transmitter and again after bouncing off a building, hill or water. The reflections arrive slightly out of phase and confuse the digital tuner, causing pixelation even when signal strength looks adequate.

Fixes include using a more directional antenna, repositioning or re-aiming away from the reflective source, or relocating the antenna to a different roof face. Multipath is common in hilly suburbs like Tallai, Mudgeeraba, Saratoga and parts of the Central Coast hinterland.

Coax does not last forever. Replace cable when you see:

• Green or white corrosion on the copper centre pin at connectors
• Cracked, sun-perished or squashed outer sheath
• Cable from the 1980s–90s still using copper-clad steel centre conductor
• Water stains on ceilings near cable runs after rain
• DIY joins with screw-on connectors instead of compression F-types

RG6 quad-shield cable is the minimum standard for digital TV today. Long runs to distant bedrooms need larger cable or amplification. Craig replaces cable with neat routing and sealed roof entries.

These quick checks save time and sometimes fix the issue without a visit:

1. Confirm the TV input is set to Antenna / Air / DTV — not HDMI or Cable
2. Firmly reseat the antenna cable at the TV and wall plate
3. Check any masthead amplifier power supply is plugged in and its LED is on
4. Run an auto channel scan / retune
5. Test another TV on the same outlet
6. Ask a neighbour if their reception is also affected (transmitter outage vs your system)
7. Note whether the problem is weather-related, time-related or constant

If those steps do not resolve it, call Craig on 0431 201 181. Describe your suburb, symptoms and what you have already tried — that helps bring the right test equipment and parts on the first visit.

There is no single "best" antenna — it depends on your suburb, transmitter, signal level and roof structure. Craig commonly installs:

• VHF/UHF combination antennas for general Gold Coast reception from Mount Tamborine
• High-gain yagi models for weak-signal hinterland properties
• Phased arrays where a broader acceptance angle helps with multipath

Signal testing on your roof determines the correct choice. Read our guide on the best TV antenna for the Gold Coast.

Yes. Many reception problems are caused by loose fittings, corroded connections, failed amplifiers or misalignment — not a dead antenna. Craig carries compression connectors, amplifiers, splitters and cable on the van and will only recommend full replacement when repair is not economical.

A quality outdoor antenna, properly installed, should last 15–20 years inland. Coastal properties may see shortened lifespan due to salt corrosion — 10–15 years is realistic without maintenance. Periodic inspection of mounts, connectors and amplifier housings extends service life.

Yes. Craig runs new RG6 cabling to additional rooms, installs wall plates and balances the distribution network so every outlet performs equally. Extra outlets are common during renovations, extensions and granny-flat builds across the Gold Coast and Central Coast.

Higher is generally better for clearing obstacles, but the correct roof plane matters more than maximum height. The antenna should aim at the intended transmitter with the shortest practical cable run to the ceiling entry point. Chimney mounts, fascia brackets and tripod masts are chosen based on roof material, wind loading and body corporate requirements.

Building-wide MATV upgrades are typically funded by the body corporate as common property. Individual unit owners pay for issues within their own lot — a faulty flylead or wall plate behind their TV. Craig can inspect the building, report to the body corporate and quote for head-end upgrades or unit-by-unit faults.

There is no practical limit with correct head-end design. Craig has installed systems serving 200+ outlets. The key is adequate amplification, balanced splitters, quality cable and regular maintenance of the common equipment room.

Yes. Modern MATV systems distribute free-to-air digital TV, Foxtel and other pay-TV services simultaneously to every outlet using separate head-end inputs and diplexing where required.

In most cases, yes. Uneven signal distribution is commonly fixed by rebalancing the network, replacing failed trunk amplifiers, upgrading the head-end or repairing damaged riser cables. Some units may receive perfect TV while others pixelate — that pattern almost always points to a distribution fault, not individual antennas. See apartment TV systems for more.

Craig recommends a professional inspection every 2–3 years for coastal buildings, or immediately after storm damage. Head-end amplifiers, power supplies and connectors fail gradually. Preventive maintenance avoids emergency outages and angry residents when the footy final pixelates.

Constant-voltage (70V or 100V) systems allow multiple speakers on long cable runs with simple volume control per zone. Ideal for restaurants, retail, schools and clubs where many speakers cover a large area from a single amplifier rack.

Yes. Craig provides independent PA design services including acoustic modelling, equipment schedules and installation drawings for architects, builders and AV companies.

Yes. We hire portable PA systems, wireless microphones and event audio with delivery, setup and pack-down across the Gold Coast and Central Coast.

Starlink often delivers faster, more consistent speeds than NBN FTTN or FTTC in areas with ageing copper infrastructure. It is especially popular in hinterland suburbs where fixed-line NBN is limited. Craig can advise based on your address and whether you also need TV antenna work while on the roof.

VAST provides free-to-air digital TV via satellite for areas without reliable terrestrial reception. Craig installs the dish, set-top box, cabling and aligns the system to the Optus satellite cluster. Registration for a VAST card is required through the official government process.

Yes. We use purpose-designed brackets for tile, metal and Colorbond roofs without compromising roof integrity. Cable entry is sealed against water ingress — critical on the coast.

Yes, where wall construction allows. Craig routes HDMI and antenna cables inside wall cavities for a clean finish. A power point behind the TV requires a licensed electrician — we coordinate where needed.

We can supply quality brackets rated for your TV weight and VESA pattern, or install one you have already purchased. Correct fixing into studs or brick is essential for safety.
