TV aerial repairs in Sawston

TV aerial repairs in Sawston

Sawston is far enough from Sandy Heath that a healthy TV aerial system matters. A house close to the mast can shrug off a corroded plug or a slightly twisted aerial, but in a low-lying village in the Cam valley the same faults are often enough to tip the picture into freezing and blocking. That’s why small problems show up here sooner: a channel that drops out on wet evenings, a bedroom TV that has stopped working, or a few missing channels after a retune.

We trace the fault methodically. We read the signal at the set, then at the wall plate, the amplifier and up at the aerial, and the point where the numbers drop is where the fault is. We fix that part, whether it is a single connector or a full realignment, retune the TVs and show you the improvement on the meter.

TV aerial faults we fix in Sawston

Storm and wind damage

Open farmland around the village lets the wind build up before it hits the rooftops. We straighten or replace bent aerials, renew rusted brackets and lashing, and make leaning poles safe.

Water in the cable or connectors

The fault we find most often. Water seeps into a cracked cable or an unsealed plug and the picture breaks up, especially in wet weather. We replace the damaged section and seal every joint.

TV aerial knocked off its line

At this distance from Sandy Heath, a small turn is enough to lose a multiplex. We realign with a meter, checking the quality on each channel group, and tighten the clamps.

Failed amplifiers and splitters

If every TV went blank together, check the amplifier first. We test it and its power supply, replace whichever has failed, and set the gain to suit the signal.

Missing channels and 4G/5G interference

If a retune leaves gaps in the channel list, an old narrow-band aerial or a weak multiplex is the usual reason. Break-up at busy times suggests interference from mobile masts, which a filter stops.

Sockets, fly leads and single rooms

A single dead TV means the fault is local to that set: a frayed lead from TV to wall, a wobbly outlet or the run of cable feeding that room. We test, find and fix it.

Repair or replace your TV aerial?

We’ll always repair when a repair will last. A new TV aerial makes sense when the old one has corroded, when it was designed for a narrow band of channels that no longer covers everything from Sandy Heath, or when it is too small for a low-lying spot and the signal has always been marginal. We show you the readings and explain why before you decide.

Trees, leaves and a valley setting

Sawston is a green village. Trees line the river, surround Sawston Hall and its grounds, and fill many of the older gardens. A tree that was well below the TV aerial’s line when it was fitted can grow into it over a few years, and in summer the leaves soak up more signal than bare winter branches do. If your picture is worse in summer, or has slowly got worse over several years, a growing tree is a likely cause. Raising the aerial on a taller pole or moving it to the other side of the roof usually solves it, and we measure each option before making any change.
