Old TV aerials rarely die in one go. They fade slowly, a channel here, a frozen picture there, until one windy evening the news won't come in at all. In Fish Hoek, salt air and the south-easter speed that up, so it pays to know the warning signs early.
Quick answer: TV aerials usually need replacing when the picture keeps breaking up after a fresh channel scan, channels vanish every time the wind picks up, or you can see rust, bent rods or a leaning mast. If the cable, wall socket and TV all check out and the problems keep coming back, the aerial itself is worn out.
Sign 1: the picture breaks into blocks or freezes
Digital TV doesn't go fuzzy like the old days. It works perfectly until the signal drops below a certain level, then the picture turns into squares, freezes or goes black with a "no signal" message.
If this happens now and then, it may be weather. If it happens most evenings, on the same channels, the aerial is probably no longer catching enough signal. Corroded rods and loose joints are the usual cause on older homes in Fish Hoek and Clovelly.
Sign 2: channels drop out when the south-easter blows
This is the classic local symptom. The wind shakes a tired mast or a loose clamp, the aerial swings slightly off target, and the signal comes and goes with each gust. When the wind dies down, everything looks fine again.
A firm, well-stayed aerial shouldn't care about wind. If yours does, the bracket has worked loose or the aerial has twisted on its pole. Our older post on southeaster myths and dish alignment covers the same problem for satellite dishes.
Sign 3: you can see damage on the TV aerial
You don't need to go up a ladder to spot this. Stand in the garden or across the road and take a good look, or zoom in with your phone camera.
- Rust or white powder on the rods and the mast
- Bent, snapped or missing elements
- The aerial pointing a different way from the neighbours' aerials
- A mast leaning, or a bracket pulling away from the wall
- Cable hanging loose, cracked or sun-bleached
- A perished rubber boot over the connector box
Sea-facing flats and homes near Kalk Bay and Glencairn take the most salt. Our guide to salt air corrosion on dishes explains why metal on the coast ages so fast.
Safety first: Check your aerial from the ground only. Please don't climb onto the roof, lean out of an upstairs window or touch a mast near overhead power lines. Roof work in Fish Hoek wind is a job for a technician with proper ladders and safety gear.
Safe checks before you blame the aerial
Not every bad picture means new TV aerials. Run through these simple checks first. They're all done indoors and take about ten minutes.
- Switch the TV off at the wall, wait a minute, and switch it back on.
- Check the aerial cable is pushed firmly into the TV and the wall socket.
- Swap the short lead between the wall and the TV for a spare one, if you have one.
- Run a fresh channel scan from the TV's settings menu.
- Plug a different TV into the same socket to rule out the TV's tuner.
- Ask a neighbour whether their picture is also bad. If it is, the problem may be the transmitter, not your aerial.
If the picture comes back after one of these, you've saved a call-out. If nothing changes, the fault is outside, on the roof or in the cable.

Some faults are cheap to fix. Others mean the aerial has reached the end of its life, and patching it only buys a few months. Here's how we usually decide.
| What you notice | Likely cause | Usual fix |
|---|---|---|
| Picture drops out in wind | Loose clamp or bracket, aerial turned | Tighten and re-aim, often no new aerial needed |
| Blocks on some channels only | Weak signal, aerial slightly off target | Re-aim, or upgrade to a higher-gain aerial |
| Rust on rods and mast | Years of salt air | Replace the aerial and fittings |
| Bent or snapped elements | Storm, birds or a fall | Replace the aerial |
| Worse after rain | Water inside the cable or connector | New cable run and sealed connectors |
As a rule, if the aerial is rusted through or the elements are bent, replacement makes more sense than repair. A new aerial with stainless or galvanised fittings will also last longer in sea air. If the house stands empty for part of the year, add the aerial to your holiday home DStv checklist.
Why TV aerials age faster in Fish Hoek
The valley sits between two mountains with the sea at both ends of the wind. Salt spray rides the south-easter in summer, and winter storms push damp air up from False Bay. Metal and cable outdoors simply wear out sooner here than they do inland.
Older homes in Sun Valley and Sunnydale often still have the aerial that was fitted when the house was built. Many have been turned, patched and re-taped over the years. By now the cable may be the weakest link, not the aerial.
Good to know: In sectional title complexes, one shared aerial or dish often feeds every flat. If your whole block has a poor picture, speak to the body corporate. Our communal systems for complexes service covers shared aerials and distribution.
What affects the cost of replacing an aerial
People often ask us about TV aerial prices, but the aerial itself is just one part of it. The bigger cost is usually the labour and fittings around it. We quote first, so you'll know before any work begins.
- Whether the old mast and bracket can be reused
- The type of aerial your signal needs
- New cable and connectors, and how long the run is
- How many TVs or rooms need a point
- Roof height and how easy it is to reach
Most of our replacements include a signal test, a proper cable run and a fresh scan on each TV. Ask our team for a current quote.
Technician tip: If you're replacing the aerial anyway, replace the outdoor cable too. Old cable full of salt and water will drag down even a brand new aerial.

How long do TV aerials last?
A good outdoor aerial can last many years inland, but coastal homes see them wear out sooner. Salt air rusts the rods and fittings, and wind loosens the mounts. If yours is old, rusty or has been patched several times, it's worth having it checked.
Can TV aerials stop working suddenly?
Yes. A storm can bend the rods or turn the aerial off target, and water can get into a cracked cable overnight. Because the signal is digital, the picture can go from perfect to nothing quite quickly. Do the indoor checks first, then call a technician.
Why does my TV say no signal on the aerial channels?
It could be a loose cable at the TV or wall socket, a TV that needs a fresh channel scan, or a fault outside on the aerial or cable. Try the indoor checks in this article first. If another TV on the same socket also shows no signal, the problem is outside.
Is it worth repairing an old TV aerial in Fish Hoek?
If the problem is a loose clamp or a turned aerial, a repair is quick and worthwhile. If the rods are rusted or bent from years of salt air, a new aerial with coastal-grade fittings is the better buy. We tell you which after testing the signal.
Do I need a new aerial for a new TV?
Usually not. A new TV can use your existing aerial, as long as it has a digital tuner and the aerial still gives a good signal. Just plug it in and run a channel scan. If the picture is poor, have the aerial and cable tested before buying a new one.
