We work for landlords, freeholders and managing agents, including mansion flats along Whetstone High Road and properties divided into separate homes. Our survey establishes the building's existing terrestrial and satellite arrangements, available access and intended services. You get an explanation of the fault or design requirement before deciding what to authorise.
Start with the distances inside the building
Whetstone's mixture of substantial houses, semis and flats means the number of dwellings alone tells us little about the cable layout. A small conversion can have a longer route to its rear flat than a larger purpose-built building has to an entire floor. We identify the routes, connections and split points that actually exist.
Cable loss changes with length and frequency. We measure at the incoming feed, distribution outputs and selected outlets to see whether the system delivers adequate quality across the required channels. Where a route is inaccessible, we record that uncertainty. We do not label buried cable as sound simply because one channel happens to display a picture.

Assess the N20 rooftop before adding gain
This is towards the northern edge of strong Crystal Palace reception, so we assess the individual roof rather than promising a standard aerial arrangement for every N20 address. Around Totteridge Lane, roof position, nearby structures and trees can influence the usable signal. The aerial must supply clean reception before distribution equipment can deliver it indoors.
We examine mounting security and weatherproof connections as well as alignment. A higher-gain aerial or masthead amplifier may be appropriate, but only where readings support that choice. Excessive gain can overload later stages. We consider both reception quality and the level needed after the building's measured distribution losses, with the full system connected.
Separate a shared failure from a private-room fault
Before the visit, tell us which flats are affected and whether their symptoms match. We can compare a known working branch with a failing one, then narrow the search through amplifiers, connectors and power supplies. If only one room fails, its wall plate or flylead may deserve attention before the shared headend is disturbed.
A typical job here: reception works at the front of a converted property off the High Road but breaks up in a rear flat. We test either end of the shared route and check intermediate joints. The resulting recommendation may concern a damaged cable or unsuitable splitter rather than a roof replacement. We explain the evidence to whoever authorised attendance.

Specify satellite capacity before residents buy receivers
Some shared installations carry terrestrial television only; others combine it with satellite and radio through an IRS. We identify the headend and outlet arrangements rather than relying on a previous sales description. Available satellite connections and receiver compatibility need checking before residents commit to new equipment.
We assess whether the installed switching supports the intended receiver, including any dSCR requirements. If changes are needed, the proposal distinguishes central equipment, branch alterations and work inside each flat. We also note any supported services that will remain unchanged. An upgrade should answer a defined requirement, not just replace an older box with a newer one.
Agree access from the High Road to the plant cupboard
We ask about loading, parking restrictions and entry arrangements when planning High Road attendance. Keys to the front door are not always enough: the amplifier may be in a locked loft, a service cupboard or a space reached through someone's home. Management should identify who holds each key before an appointment is confirmed.
For properties towards Swan Lane Open Space and Totteridge, we still inspect the actual working route and safe equipment access. If external alterations face planning or conservation restrictions, the necessary consent checks come first. We agree protection of communal finishes, cable penetrations and relevant fire-stopping requirements with the building's responsible contact.
Make a written scope useful to the freeholder
Our report connects the reported problem to test locations and findings. It includes readings and photographs of relevant accessible equipment, explaining where the signal deteriorates and what remains untested. We distinguish an immediate repair from longer-term renewal so that an urgent decision need not become an open-ended refurbishment.
The fixed written quote states the proposed parts, work and checking arrangements. Where several flats need new cabling, we identify those access requirements and any likely interruption. Extra work uncovered during investigation is referred back for approval. We do not treat permission to survey as unlimited authority to replace the communal system.
Use maintenance readings as a reference point
A well-documented handover helps the next engineer identify a change instead of starting from guesswork. We label agreed equipment and routes, note the services supported and record completion measurements. If some flats were unavailable, we specify which outlets were checked rather than describing the whole property as tested.
For ongoing maintenance, we can agree inspections of accessible supports, weather seals, cable condition and distribution equipment. Comparing readings over time can reveal deterioration before a complete outage. The maintenance agreement defines visit frequency, priority callout arrangements and charges for additional parts or labour; priority does not imply an unconditional attendance time.

Tell us the building layout when you call
Ring free on 0800 206 2385, or WhatsApp 07595 292534 with the address, approximate flat count and affected services. We provide free advice, and planned installation or renewal starts with a free site survey. An instructed fault-finding visit is separately scoped and priced before you agree to it.
Finchley Aerials and Satellites is based at Britannia Road, Finchley N12 9RU. We have 25 years' experience and answer Mon-Sat between 8am and 7pm. We try to offer same-day service when practical, with outdoor work limited by sunset and safe conditions. Your nominated representative receives the findings and any request for further authorisation.
