TV Antenna, Satellite & Starlink Installation Across the Mornington Peninsula

The transmitter split: north versus south

The northern Peninsula — Frankston, Frankston South, Langwarrin, Mount Eliza, Mornington and most of Mount Martha — looks north-north-east to Mt Dandenong, between roughly 40 and 60 kilometres away. Mt Dandenong broadcasts the Melbourne networks on VHF channels 6, 7, 8, 11 and 12 with horizontal polarisation at 50 kW. Homes here need a combination antenna with proper VHF elements, mounted horizontally and aimed at about 30 degrees.

Further south the picture changes. Arthurs Seat rises over 300 metres straight out of the bay and blocks or weakens the path to Mt Dandenong for much of Dromana, McCrae and the bay side of the ridge. Two low-power repeaters fill those gaps. The Arthurs Seat repeater rebroadcasts the same networks on UHF channels 40 to 45 with horizontal polarisation, aimed at Safety Beach and the bay side of the hill. The Rosebud repeater, on the council offices site, transmits the same UHF channels with vertical polarisation at just 25 watts, covering pockets around Rosebud and Capel Sound.

Because the repeaters are UHF and the main transmitter is VHF, they need different antennas. Because the Rosebud repeater is vertical and the Arthurs Seat repeater is horizontal, they need different mountings too. The single most common fault we find on the southern Peninsula is an antenna built or mounted for one site and pointed at another — often after a like-for-like replacement copied an antenna that was never right.

Out at Rye, Blairgowrie, Sorrento and Portsea, the distance to Mt Dandenong reaches 70 to 80 kilometres, and the dunes and back-beach ridges shadow ocean-side streets. Reception varies sharply between the bay and back-beach sides of the same town, and between single- and two-storey homes. We meter every candidate site from your roof before deciding.

Salt, wind and coastal hardware

Port Phillip on one side and Western Port and Bass Strait on the other mean almost every Peninsula roof is within reach of salt air. Salt attacks antenna elements, baluns and any connector that is not fully sealed. The signal fades gradually — usually one network first — and then fails after a storm. A ten-year-old antenna in Rosebud is often in worse condition than a twenty-year-old one in Melbourne's east.

Our standard Peninsula install uses an Australian-made antenna with a sealed balun, stainless or galvanised mast hardware, weather-booted compression connectors and self-amalgamating tape on every join. Those details add little to the job and years to the installation. Exposed roofs on the ocean side get heavier masts and, on taller installs, guy wires.

Steep Colorbond and tiled coastal roofs, two-storey beach houses and multi-point holiday homes with a TV in every bedroom are typical here. A distant signal split six ways needs a properly sized distribution amplifier; without one the furthest rooms fail first.

Holiday homes and property managers

A large share of Peninsula homes are holiday houses and short-stay rentals. Faults go unreported for months, then a guest arrives to a blank screen. We work with owners and property managers across the Peninsula, meet trades on site, send photos and meter readings of the fix, and quote at a fixed price before any work.

Mornington Peninsula by the numbers

We cover 65 suburbs and localities in Mornington Peninsula. Distances to the main transmitter range from 39 km (Langwarrin) to 80 km (Cape Schanck). Across the region, the sites worth metering are: Mt Dandenong (65 suburbs), Mt Tassie (Latrobe Valley) (10 suburbs), Arthurs Seat repeater (7 suburbs) and Rosebud repeater (5 suburbs).

By housing and terrain, the region breaks down as 21 coastal salt belt, 19 rural acreage fringe, 14 island, western port & bass coast exposure, 9 foothills & escarpment shadow and 2 established middle-ring suburb — which is why one standard antenna does not suit every street.
