TV aerial repairs in Harlow
A lot of Harlow’s housing went up in the 1950s and 1960s as the new town grew, and many TV aerials and cables have been patched and extended ever since. Over the years connectors oxidise, cable jackets split, brackets loosen on chimneys and wall plates, and aerials creep out of line with Crystal Palace or Sandy Heath. The symptoms build slowly: a stutter on one channel, then a few more, then a blank screen on a wet evening.
Most of these problems are cheaper to repair than you might fear. We measure the signal at the TV, the wall socket, the amplifier and the aerial in turn, and the point where the reading falls tells us which part has failed. We repair or replace that part, recheck every room, and show you the figures.

TV aerial faults we put right in Harlow

Storm and wind damage
Tall chimneys, roofs on the edge of town and homes facing open green wedges catch the full force of a gale. We straighten or replace damaged aerials, renew lashing wire and clamps, and secure or remove masts that have started to lean.

Water in the cable or connectors
The fault we see most. Rain gets through a split jacket or an unsealed plug, and the picture breaks up until the joint dries. We cut back to sound cable, fit sealed connectors and weatherproof the joint.

TV aerial knocked off its line
A small twist away from the transmitter costs you channels. We reset the aerial on a meter, whether it faces Crystal Palace or Sandy Heath, and tighten everything so it holds.

Failed amplifiers and splitters
Every set going blank together points to the loft amplifier, its power supply or a splitter. We test each, replace the faulty one and set the gain to suit the signal you actually receive.

Missing channels and 4G/5G interference
Lost channels after a retune often mean the aerial can’t receive every multiplex. Picture trouble at busy times of day suggests interference from phone masts, which a filter removes.

Single rooms, sockets and fly leads
If only one TV is affected, the cause is nearly always near that set: a kinked fly lead, a loose wall plate or a bad joint in that room’s cable. We find it quickly and fix it.
Should you repair or replace the TV aerial?
We repair whenever the fix will last. A new TV aerial is the better choice when the old one has corroded or lost elements, when it was made for a channel group that misses part of today’s Freeview, or when the mast and bracket need replacing and the aerial is nearly worn out. You’ll see the readings and hear our reasons before you decide.

Communal TV aerial faults in Harlow’s flats
Harlow’s flats range from The Lawn in Mark Hall, completed in 1951 as the UK’s first residential tower block, to low-rise blocks in every neighbourhood and newer apartments near the town centre. When a shared system fails, several households lose their picture at once. The usual culprits are a failed head-end amplifier, water in the riser cable, or a faulty outlet that drags down others on the same run. We trace the fault floor by floor, repair it, and leave readings for the landlord or managing agent, who is normally responsible for the shared equipment.

Harlow questions
All my TVs say ‘no signal’ at the same time. What’s wrong?
When every set fails together, look first at the loft amplifier: is it plugged in and is its light on? If so, the amplifier may have failed, the main cable may be damaged, or wind may have moved the aerial. We can test each and fix the one at fault.
Why does my picture freeze when it rains in Harlow?
Damp in a cable or connector is the usual cause. Water enters a split or a poorly sealed joint and weakens the signal until it dries. Replacing that section and sealing the connectors cures it.
Can my TV aerial be repaired, or do I need a new one?
Most faults are repairs: a connector, a length of cable, an amplifier or a realignment. We only suggest a new aerial when the old one is corroded, too narrow-band or badly damaged.
Our block’s communal TV aerial has stopped working. Who should we call?
Tell your landlord or managing agent, who usually looks after the shared system. We can attend for them, find the fault and repair it.
Can you give me a report for an insurance claim?
Yes. After storm damage we can write down what we found and what we did, which most insurers ask for. Check your policy to see whether TV aerials are covered.
