We are Finchley Aerials and Satellites. Our work covers new aerials, replacement cabling and extra television outlets across N21. With 25 years' experience, we know that buying the biggest aerial is not a substitute for finding the right mounting point and checking what reaches the television.
Find a reception position before choosing the hardware
We start by asking which rooms need television and whether an existing aerial has ever worked reliably. Then we assess the building, surrounding roofs and practical access. Height can help on a valley-side property, but an unnecessarily tall mast adds load without necessarily improving the signal. We select the support and aerial together.
Crystal Palace is the first transmitter we assess here. We compare signal quality as well as strength, because a powerful reading can still hide reception errors. If another alignment is worth considering, we explain the channel implications before fixing anything permanently. Your neighbour's aerial direction is a clue, not a specification.

Keep channel choice in the conversation
The Alexandra Palace relay offers fewer services than the main Crystal Palace transmitter. If a difficult location makes the relay an option, we discuss the programmes you expect to receive. We do not hand over a picture on one channel and leave you to discover that another group is unavailable.
Freeview channels arrive in groups called multiplexes. We check reception across those groups rather than judging the installation on a single broadcast. Your television also needs the appropriate tuner for the services you want; an aerial cannot add HD decoding to an older set that lacks it.

A loft aerial is an option to test, not a promise
In an inter-war semi, accessible loft space can make an indoor installation appealing. It avoids an exposed outdoor aerial and may simplify future access. However, roof coverings, foil insulation and nearby water tanks can reduce reception. We take readings in the proposed position rather than assuming the loft will work.
For Edwardian villas and cottages around Winchmore Hill Green, an external position may provide a cleaner path. We inspect the proposed fixing surface and consider the appearance from ground level. Where conservation controls or listed status affect the property, we ask you to settle the required permissions before external alterations.
Make the cable route part of the installation plan
Before drilling, we walk through the route from the aerial to your viewing position. A short cable draped over a roof edge is not a tidy solution. We plan supported runs, suitable bends and protected entries, taking care around original brickwork and the finishes you want to retain.
Existing coax can sometimes stay, provided testing shows it is suitable and sound. We look for water damage, crushed sections and unnecessary joins. New screened cable is secured without squeezing its insulation, and outside connections are weatherproofed. Indoors, we agree socket positions so furniture need not hide an awkward trailing lead.
Supply the bedroom without spoiling the lounge signal
Adding a second or third outlet changes the load on an aerial system. We work out how the feed will divide and measure the result at each finished socket. A passive splitter may be sufficient; amplification is considered only when the measured signal and cable losses justify it.
In a house conversion, we first establish whether the incoming aerial serves your home alone. Shared feeds need an agreed approach with the owner or managing agent. We do not attach extra distribution equipment to a communal line simply because a cable happens to be within reach of your flat.
Leave room for safe access and later maintenance
Please tell us about rear-only access, locked side passages or a loft hatch above fitted furniture when you book. Around Grovelands Park, mature planting can also affect where we can safely work. Photographs help us prepare, although the final access decision is made at the property.
We assess brackets, masonry and any existing mast before reuse. If the proposed position cannot be reached safely with the planned equipment, we explain the alternatives and any additional access arrangements. We will not balance an installation on an unsound chimney merely to keep an old cable route.
Prove the result at the television
Our final checks follow the signal indoors. We measure the completed outlets, connect the television and tune it to the intended transmitter. We check the available channel groups and explain any equipment limitation. If the picture is unstable, we investigate rather than relying on repeated automatic tuning.
Where measurements indicate mobile-network interference, we assess suitable filtering. A filter is not a routine cure for every missing channel, and a booster cannot restore information lost in a damaged cable. We show you the working setup and explain which components need power, so everyday use remains straightforward.
Arrange your N21 installation with a clear scope
Call free on 0800 206 2385 or send your postcode and access photographs by WhatsApp to 07595 292534. We answer Monday to Saturday, 8am-7pm; outdoor work continues only until sunset. Same-day attendance is possible when the diary, daylight and access requirements allow it.
Our base is Britannia Road, Finchley N12 9RU. We offer free advice and provide a fixed written quote describing the proposed aerial, cable work and outlets. You receive a clear price before work starts, with any change discussed rather than quietly added to the job.
