TV Antenna Repair Melbourne — No Signal, Pixelation & Missing Channel Fixes
Storm damage, corroded baluns, water-logged coax, dying amplifiers — most reception faults aren't the antenna (aerial) itself. Our technicians diagnose with calibrated signal meters and fix the actual root cause, not just the symptom.

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
- 1
Spectrum Analyzer Fault Tracing
We connect our calibrated digital meter to your roof antenna and wall plates to locate where signal drops occur.
- 2
Component-Level Repair on the Spot
We carry replacement baluns, masthead amplifiers, splitters and masts directly on the service vehicle.
- 3
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.
