If you live within a few kilometres of the coast in Perth's northern suburbs, there's a good chance you've dealt with dodgy TV reception at some point. Pixelation, dropouts during windy weather, channels disappearing completely — sound familiar?
It's not your TV. It's almost certainly your antenna.
After years of working across suburbs like Mindarie, Quinns Rocks, Clarkson, Butler, Jindalee and Alkimos, we've seen the same problems come up over and over again. Here's what's actually going on and what you can do about it.
Salt Air Destroys Antennas Faster Than You'd Think
The biggest killer of TV antennas in coastal Perth is salt corrosion. The salt-laden air that blows in off the Indian Ocean eats through cheap antenna components within a few years. The connections corrode, the balun (the little box that connects the antenna to the cable) stops working properly, and your signal goes from perfect to unwatchable.
If your antenna was installed by the builder when your house was built, there's a decent chance they used the cheapest gear available. Builder-grade antennas and cabling are designed to pass inspection, not to last 15 years in a coastal environment.
The fix is simple: use marine-grade or Australian-made antennas designed for coastal conditions, with quality connections and proper weatherproofing. We use antennas that are built for exactly this environment — they cost a bit more upfront but they'll still be working perfectly in 10 years.
Wind Is the Second Biggest Problem
Perth's northern corridor cops some serious wind, especially in the afternoon sea breeze season. If your antenna isn't mounted properly — or if the mast has loosened over time — the antenna moves in the wind. Even a small amount of movement can cause the signal to drop in and out.
Signs your antenna has a wind problem:
- The picture pixelates then comes good, then pixelates again
- You can hear the antenna or mast rattling on the roof
- Reception is fine on calm days but breaks up when it's breezy
Sometimes it's as simple as tightening the mounting brackets and re-aiming the antenna. Other times the mast itself needs replacing — especially the old galvanised steel ones that have rusted through at the base.
Splitter and Cabling Issues
Got multiple TV points in the house? Every time you split a TV signal, you lose some strength. A four-way splitter means each TV is only getting about a quarter of the original signal. Add in old or damaged RG6 cabling, and the signal reaching your TV might be too weak to maintain a stable picture.
This is particularly common in older homes around Joondalup, Hillarys, Sorrento and Padbury where the original cabling might be 20+ years old. The cable itself degrades over time, especially where it's exposed to heat in the roof space.
The solution is usually a distribution amplifier (sometimes called a masthead amplifier) installed at the antenna. This boosts the signal before it's split, so every TV in the house gets a strong, clean picture. It's a relatively cheap fix that makes a massive difference.
The "It Was Fine Until..." Problem
We get a lot of calls from people saying their TV was perfect for years and then suddenly went bad. Nine times out of ten, it's one of three things:
New construction nearby. A two-storey house or apartment block going up between you and the transmission tower at Carmel or Bickley can block or reflect the signal. The northern suburbs are growing fast, and new buildings change the signal landscape all the time.
Trees have grown.That little tree in the neighbour's yard is now a big tree sitting right in the signal path. Trees — especially when they're wet — can significantly attenuate TV signals.
Equipment failure.Baluns fail. Amplifiers fail. Connections corrode. If everything worked fine for 8 years and suddenly doesn't, something has probably reached the end of its life.
What a Proper Antenna Install Looks Like
When we install a new antenna, we don't just slap something on the roof and hope for the best. Here's what we do:
We use a signal meter to find the strongest signal direction and check all available channels. We install Australian-made antennas rated for coastal conditions. We use quality RG6 quad-shield cabling with proper compression fittings — no push-on connectors that work loose over time. If you've got multiple TVs, we install a masthead amplifier powered from inside the house. And we weatherproof every connection on the roof.
The result is a clean, strong signal to every TV in your house that doesn't fall apart the first time the Fremantle Doctor blows through.
