Aerial repairs and measured fault-finding in Barnet
A typical job here: in Barnet we repair an inter-war semi in New Barnet where upstairs HD channels break up every evening. A failing amplifier power supply is dropping out as it warms up. We replace it and retest both outlets.
We check the mast, downlead, connectors, sockets and amplifier supply, recording MER/BER meter readings at the aerial and indoors. We test for 4G/5G interference and fit a suitable filter when the measurements establish the need. We secure outdoor cable and seal connections before checking the picture again.

What you can expect
Call Finchley Aerials free on 0800 206 2385, Mon–Sat 8am–7pm. We offer a free site survey and a fixed written quote, with a clear price before work starts. We explain the fault, keep sound equipment and test the repaired feed at your television.
Meter-led signal fault finding in Barnet
We trace picture breakup in Barnet with a calibrated meter, recording MER/BER readings across the available multiplexes at the aerial and television socket. We compare signal quality before and after the amplifier, splitter and cable runs, isolating the failed component without replacing sound equipment. We test amplifier power supplies and connectors as part of the same sequence.
High Barnet’s ridge and the dips around New Barnet demand different alignment checks. In Victorian villas and inter-war semis, we compare the incoming signal with each room’s feed before deciding which component needs attention. We check for 4G/5G interference and fit a filter only when the measurements establish the need. After the repair, we repeat the readings at every agreed outlet and show you the results.
TV aerial installation with a tested roof position in Barnet
We do different surveys on the High Barnet ridge and in New Barnet’s lower streets. A compact aerial suits a clean ridge-top signal; a lower roof needs careful positioning before we decide on gain or mast height.
We start with Crystal Palace transmitter reception and compare the Alexandra Palace relay where the site warrants it. The relay carries fewer channels; we explain that difference before fitting anything. We use double-screened WF100 cable, sound fixings and weatherproof entries, then check every connected room. Amplification is specified against measured distribution losses.

Freeview tuning and missing-channel repairs in Barnet
At homes around Barnet Market, we check every multiplex before saving a fresh channel list. One working BBC channel tells us nothing about the quality available on the other broadcast frequencies.
We check signal quality across all available multiplexes, including the HD services, and confirm the television supports the broadcasts you want. We repair the feed before retuning. Repeated channel scans on a faulty cable lose stored services and leave the original fault untouched. We finish by showing you the working channel list and checking each connected set.
Satellite dish installation and repairs in Barnet
At larger homes towards Hadley Wood, we agree the number of receivers before choosing the dish equipment. Each receiver’s tuner requirements determine the feeds and LNB arrangement.
We test dish alignment, LNB skew, connectors and cable for satellite reception at Astra 28.2°E. Sky Q wideband feeds and conventional satellite connections serve different receiver arrangements; we confirm your model first. For Freesat, we check the receiver’s LNB requirements, then test each requested feed and protect exterior connections against water.

TV wall mounting with proper structural fixings in Barnet
In a Barnet villa, an original chimney breast and a modern partition need completely different fixings. We inspect the proposed wall and agree viewing height from your usual seating position.
We match the bracket to the television’s weight and VESA pattern, check for concealed pipes and wiring, and leave ventilation space. We agree cable routes before drilling and keep connected equipment accessible. A new mains socket goes to a qualified electrician. We finish by checking the bracket, screen position and every connected source with you.
Starlink mounting with a clear-sky assessment in Barnet
Near Hadley Wood, branches above the roofline are the first thing we assess. We check the broad sky view Starlink needs before proposing a pole, wall bracket or cable route.
We confirm the terminal model before selecting compatible mounts and routing the manufacturer’s cable. We support the cable, respect bend limits and weatherproof the building entry. Once mounted, we check the connection and router position with you. We also explain where thick walls limit indoor Wi-Fi and discuss wired access points for rooms beyond reliable coverage.
Working around Barnet homes, roofs and signal paths
High Barnet, New Barnet and the roads towards Hadley Wood need separate reception decisions. We also plan ladder access around porches, side extensions and garden rooms, keeping exterior cable routes clear of opening windows.
Our nearby work also takes us through Whetstone, Southgate, Enfield and Mill Hill. We bring the meter to each property and make decisions from that address’s readings. Before leaving, we show you what we changed, test the agreed outlets and leave the cable routes tidy.
