Do I need a TV signal amplifier? Melbourne reception decoder

"Just put an amplifier on it" is the most over-used fix in Melbourne TV reception. Sometimes it's the right answer. Often it's the reason your picture got worse.

When an amplifier *does* help - Long cable runs (over 30m of coax) - Multiple TV points (more than three off one antenna) - Genuinely fringe signal areas: outer Mornington Peninsula, parts of the Dandenong Ranges, rural West Gippsland - After a powered splitter: the dB loss adds up

When an amplifier makes things *worse* - Strong-signal suburbs (Box Hill, Glen Waverley, Mount Waverley): adding gain *clips* the signal and causes pixelation that looks identical to weak signal - Adjacent transmitter interference: amplifying noise alongside the wanted signal doesn't help - Already-amplified MATV systems (apartments): a second amp creates intermodulation distortion

Masthead amp vs distribution amp - **Masthead amp** sits at the antenna, before any cable loss. Best for fringe areas — boosts the cleanest version of the signal. - **Distribution amp** sits indoors, after the trunk cable, and feeds multiple TV points. Best for homes with 4+ TVs.

How we decide We meter the signal at the antenna, after the cable, and at each wall plate with a calibrated digital meter. The numbers tell us whether you need more gain, less gain, or different equipment entirely.

DIY amplifier from Bunnings — yes or no? The cheap two-port distribution amps work fine in low-density situations. The masthead amps need a power injector at the wall and proper weatherproofing — a job for a professional install.
