We are Finchley Aerials and Satellites. Our 25 years of experience helps us plan careful repairs around period buildings and shared systems. We explain what we find, what can remain in service and why any proposed replacement is necessary.
Hilltop reception is not the whole NW3 picture
Hampstead's higher ground can offer excellent reception, while homes in dips have a different outlook towards the transmitter. We measure at your property rather than inferring performance from a nearby roof. A building close to Hampstead Heath can still have a damaged cable despite an apparently favourable position.
Tell us whether reception has always been marginal or stopped abruptly. Those histories lead to different checks. We separate a long-standing positioning issue from a recent component failure, and avoid prescribing a taller mast before establishing what the present aerial and distribution system actually deliver.
Repairing around period fabric
Georgian, Victorian and Arts and Crafts houses can have cable routes hidden by successive alterations. We agree how to inspect those routes without casually damaging joinery or plaster. If a replacement lead needs a new path, you see the proposed entry point and visible sections before drilling starts.
Listed status and conservation-area considerations matter when external equipment or its position changes. We identify the relevant permission questions and discuss the proposed alteration clearly. Repairing existing equipment does not give us licence to assume every new bracket or cable run is acceptable without checking.
Use the meter to locate the loss
Our checks compare signal level with digital quality across the broadcast multiplexes. A television can report substantial strength while errors still break up the picture. We examine readings through the feed, amplifier and outlet to identify where the installation stops delivering usable reception.
If one room fails but another remains reliable, the branch between them deserves attention before the roof. We inspect sockets, flyleads and splitters, retaining components that pass the checks. You receive an explanation of what failed rather than a list of replacement equipment unrelated to the measurements.
Damp joints on an exposed route
Rain-dependent faults prompt an inspection of external coax, connectors and entry points. Moisture can move within the cable, so the wet end may not reveal where the leak began. We assess the affected length instead of assuming a fresh connector will permanently resolve the problem.
Where renewal is agreed, screened WF100 cable is secured along a planned route and external joints are protected against weather. Around Hampstead Village, the practical route may involve shared areas or restricted access. We establish permission and access arrangements before arriving to undertake the agreed repair.
Mansion blocks require a clear boundary
In a block, your television may connect to equipment controlled by a freeholder or managing agent. We establish ownership before altering the shared feed. If neighbours have matching channel loss, please mention it; that information helps arrange access to the right distribution stage rather than testing one flat in isolation.
We can check accessible equipment within the authorised scope and explain when a communal investigation is needed. Shared amplifiers are not adjusted speculatively to solve one outlet. Any building-wide proposal is discussed with the responsible representative, including which branches can be measured and what remains inaccessible.
Aerial direction and safe support belong together
If alignment needs attention, we first assess whether the mounting will hold its position. Loose lashings, corroded brackets or defective masonry can defeat a simple adjustment. We describe the safety issue separately from reception and will not fasten equipment onto an unsound chimney.
Crystal Palace reception is assessed against the available alternatives at the site. A relay can offer a reduced selection, which matters when missing channels prompted the visit. We explain that trade-off before proposing a different direction. A better meter reading alone does not justify leaving you without expected services.
A booster is not a universal repair
We test amplifier power and examine whether existing gain is appropriate. Too much amplification can be as unhelpful as too little. Where mobile signals are implicated, we compare suitable filtering and inspect cable screening; a filter has a specific job, not magical powers over every reception fault.
After the agreed work we remeasure the repaired path and check the affected programmes at the designated sockets. We retune if needed once reception is restored. We also explain remaining limitations, including any untested branches or access-dependent work, so the handover is useful rather than just a quick glimpse of one channel.
Book with permission and access in mind
For free advice, ring 0800 206 2385 during Monday-Saturday opening hours, 8am-7pm. WhatsApp 07595 292534 is another way to send the postcode and symptoms. Tell us about roof restrictions, managing agents and parking arrangements so the appointment can be planned realistically.
Our address is Britannia Road, Finchley N12 9RU. Same-day service is offered where possible, subject to the diary and safe access. On-site tasks may continue until sunset. We set out a fixed written quote, and you get a clear price before work starts rather than an unexplained repair bill.
