Antenna technician diagnosing a faulty TV signal with a digital signal meter on a Melbourne rooftop

Local, registered, guaranteed.

  • ACMA-registered cablers, fully insured
  • Australian-made antennas, 25-year warranty
  • Signal meter on every job — no guesswork
  • All work guaranteed. Owner-operated since day one.

What's included

Done properly, the first time

  • Digital signal diagnostic testing to isolate balun corrosion, perished coax or amplifier failure
  • Replacement of rusted outdoor F-connectors and weathered coaxial cabling with RG6 quad-shield
  • Masthead amplifier repair, power injector troubleshooting and 4G LTE filter installation
  • Realignment of shifted antennas to peak transmitter azimuth following heavy winds or storms
  • Verification of signal quality (minimum 45 dBuV signal level, MER > 25 dB) at every outlet

Our process

Three steps from booking to done

Spectrum Analyzer Fault Tracing

We connect our calibrated digital meter to your roof antenna and wall plates to locate where signal drops occur.

Component-Level Repair on the Spot

We carry replacement baluns, masthead amplifiers, splitters and masts directly on the service vehicle.

Multi-Point Signal Validation

Every channel is tested across all connected televisions in the house to verify zero pixelation.

Recognise the symptom?

Common TV reception symptoms — and what they mean

No signal on TV

Symptom: TV says 'No Signal' on every channel

Likely cause: Usually a snapped antenna cable, storm-damaged element, or failed masthead amplifier — we meter the line and replace the failed component.

TV picture pixelating or breaking up

Symptom: Squares, freezing, audio glitching

Likely cause: Marginal signal level — typically a corroded F-connector, perished coax, or oversized splitter. We meter every joint to find the culprit.

Some TV channels missing

Symptom: Most channels work but a few are gone

Likely cause: Antenna gain on specific frequencies dropping below threshold — usually an old or under-gain antenna for your distance from the transmitter.

TV signal dropping in and out

Symptom: Reception comes and goes

Likely cause: Often atmospheric ducting (warm evenings), a loose F-connector, or 4G/5G interference. We test and install a 4G filter where needed.

4G or 5G interference on TV

Symptom: Reception worsened after a new mobile tower was built nearby

Likely cause: Mobile carrier signal overlapping the digital TV band. A masthead-mounted 4G filter resolves it.

TV reception bad after storm

Symptom: Worked fine yesterday, no signal today after weather

Likely cause: Antenna twisted, mast bent, or water ingress at the joints. Often visible from the ground — we'll inspect and quote repair vs replace honestly.

TV freezing or stuttering

Symptom: Picture pauses every few seconds

Likely cause: Bit-error rate above threshold — same root cause as pixelation, diagnosed with a calibrated digital signal meter.

TV reception worse since adding extra rooms

Symptom: Original TVs worked, new outlets are weak

Likely cause: Splitter losses — every extra TV outlet halves the available signal level. We size or replace the splitter and add a distribution amp if needed.

Why people call Master Antenna

Small, owner-operated and accountable — the opposite of a franchise call centre.

You speak to the technician

No 1300 number, no sales desk. The person who answers is the person who turns up, quotes the job and fixes it.

Signal-meter diagnosis

We measure signal at the antenna with a calibrated meter, so we fix the real fault — antenna, cable, splitter or TV — not guess.

Fixed price before we start

You get the price on the spot after the test. No hourly rate, no add-ons at the end, and $0 call-out when you go ahead with the repair.

Same day, 7 days a week

Call before 11am for the best chance of a same-day visit. Open 8am–9pm, weekends included.

Frequently asked

Common antenna repair questions

How do I fix no signal on my TV?

Most no-signal calls trace to a snapped or corroded outdoor cable, a failed masthead amplifier or a storm-damaged antenna element. We meter the line at the wall and the antenna to pinpoint it on the same visit — typically fixed within an hour.

Why does my TV pixelate?

Pixelation almost always means signal quality (MER) has dropped below the digital threshold — corroded balun, water in the coax, or an oversized splitter. We measure quality at every wall point and replace the faulty link.

Why are some of my TV channels missing?

Either the antenna gain has dropped on specific frequencies (an ageing or under-gain antenna for your distance from the transmitter), or the TV needs a fresh retune after a transmitter change.

Does 5G interference affect TV reception?

Yes — Telstra's C-band 5G rollout has caused real reception issues for some Melbourne households. A masthead-mounted 4G/5G filter blocks the mobile band and restores clean digital TV signal.

Do I need a new antenna or just a repair?

Often the antenna is fine and the fault is downstream. We test before we quote — most repair calls are a fraction of the cost of a new install.

Do you repair antennas damaged by storms or trees?

Yes. We can also provide a written report and photos suitable for home insurance claims.

How quickly can someone come out?

Same-day if you call before 11am. Otherwise we'll confirm a next-morning slot at booking.
