Pixelation, no signal or missing channels? Master Antenna diagnoses the exact fault with a digital signal meter — then gives you an honest recommendation: repair or replace. Same-day service, fixed price.
Verified Customer Reviews
“Lost SBS and Channel 9 completely whenever it rained. Another company quoted me $700 for a brand new antenna over the phone. Master Antenna came out, hooked up their digital signal meter, and found it was just water entering a cracked coax connector and balun. Repaired it in 45 minutes for a fraction of the cost. Honest and professional.”
“Every evening at 7pm our TV would start stuttering and glitching. Master Antenna identified the problem immediately — mobile phone tower 5G interference on the UHF band. Installed a Kingray 4G/5G bandpass filter and re-terminated the splitters. Crystal clear picture on every channel ever since.”
“High winds knocked our antenna mast sideways during a winter storm and snapped the bracket. Master Antenna attended same-day, installed a heavy-duty galvanised mount with guy wires, re-aligned the aerial to Mount Dandenong, and tuned all three TVs. Prompt and tidy.”
Digital television reception does not degrade gracefully into static the way old analogue TV used to. Instead, it hits a “digital cliff” — as soon as signal strength (dBuV) drops too low or signal quality (Modulation Error Ratio, or MER) falls below threshold, the picture instantly pixelates, stutters, drops audio, or flashes “No Signal”. Guessing the cause by buying random booster boxes or jiggling cables rarely works. Master Antenna diagnoses reception faults with a calibrated digital spectrum analyser, measuring signal strength and bit error rates directly at your antenna and at every indoor outlet to pinpoint the exact failure point.
In more than half of the repair calls we attend across Melbourne and Gippsland, the antenna itself is physically intact. Reception failures commonly originate downstream: water leaking into cracked coaxial cabling, corroded balun transformers, damaged splitters, or blown masthead amplifier power supplies. If your antenna is 15+ years old and corroded beyond repair, we explain why and present fixed replacement options.
As mobile networks expand, 4G and 5G cellular towers broadcast on frequencies immediately adjacent to digital TV channels. This strong cellular signal can easily overpower older TV tuners and masthead amplifiers, causing severe pixelation. We test for this interference and install professional 694MHz LTE low-pass filters to block cellular frequencies entirely, restoring perfect reception.
Our mobile service vans carry comprehensive repair stock — Australian-made Matchmaster baluns, Kingray shielded masthead amplifiers, RG6 quad-shield coaxial cable, and heavy-duty galvanized roof brackets. We diagnose, quote, and complete your repair in a single visit, followed by a full channel retune on every TV in your home.
From digital spectrum analysis and cable testing to hardware replacement and channel retuning — all in a single visit.

These are the issues we diagnose and resolve most often — usually in a single visit.
High winds push loose antenna mounts off alignment, while rainwater penetrates cracked coaxial outer jackets or corroded balun housings, causing signal loss.
When all channels vanish at once, the issue is almost always a blown masthead amplifier power injector, disconnected splitter, or snapped lead-in cable.
Mobile network towers broadcasting near the 700MHz UHF band overload TV tuners during peak evening mobile data usage. A calibrated bandpass filter eliminates the interference.
If reception is fine in the living room but broken in the bedroom, the antenna is healthy but an internal splitter, old RG59 cable run, or wall socket has failed.
Homeowners experiencing intermittent pixelation, stuttering audio, or missing channels like Channel 7, 9, 10, ABC, or SBS.
Rooftops where high winds, falling tree branches, or severe weather have knocked the mast or broken aerial elements.
Properties with 15+ year old analog aerials, brittle ribbon cables, or unshielded splitters requiring digital upgrading.
Fast turnaround same-day repairs for landlords, property managers, and body corporates with full tax invoices provided.
Everything you need to know about professional TV antenna repair across Melbourne and Gippsland.
Digital TV broadcasts operate on a digital cliff. When the signal strength (dBuV) or digital modulation quality (MER) drops below operating thresholds, picture doesn't get static — it instantly freezes, pixelates, or shows 'No Signal'. Common root causes include water in damaged coaxial cabling, corroded balun transformers, a failed masthead amplifier power supply, or antenna misalignment from wind.
In over half of our repair calls, the antenna itself is physically sound. Faults are commonly located downstream — such as cracked outdoor cabling, corroded splitters, loose wall plates, or dead power injectors. We connect a digital spectrum analyser directly to your aerial to test reception before quoting, ensuring you only pay for what actually needs fixing.
Wind causes loose antenna mounting brackets to sway, swinging the narrow reception beam away from the Mount Dandenong transmitter. Rain causes problems when water penetrates perished coax cable or unsealed balun terminals, creating short circuits and massive digital signal attenuation.
Mobile network operators use cellular frequencies adjacent to digital TV broadcast channels (above 694MHz). Powerful nearby 4G and 5G mobile towers can overpower TV tuners and masthead amplifiers, causing severe pixelation. We install calibrated bandpass LTE filters that block mobile tower frequencies while letting TV channels pass cleanly.
Most standard antenna repairs — including digital meter diagnosis, balun replacement, coax re-termination, mast realignment, and TV retuning — are completed in 45 to 90 minutes on our first visit.
We quote upfront fixed pricing in writing before any repair work commences. No surprise fees, no hidden hourly rates, and no pressure. If a repair isn't economically viable, we explain why and quote replacement options transparently.
Yes. Missing specific channel networks usually means that particular frequency band (VHF Band III or UHF) is being attenuated by a faulty diplexer, wrong antenna orientation, or interference. Our spectrum meter measures individual frequency channels to restore all free-to-air networks.
