TV aerial repairs and installation in Swiss Cottage

Swiss Cottage sits along the busy spine of Finchley Road and Avenue Road, dominated by tall mansion blocks and post-war purpose-built flats interspersed with older Victorian villas on the quieter side streets such as Eton Avenue and Fairhazel Gardens. The taller blocks along Finchley Road throw genuine shadow onto lower flats and neighbouring rooftops, so reception towards Crystal Palace to the south-east can vary sharply between a top-floor flat with a clear run and a ground-floor flat looking straight at the building opposite. Roof access on these blocks is usually restricted to a managing agent's contractor rather than open to residents, which shapes how any fault gets fixed far more than the technical reception picture does.

Purpose-built blocks from the 1930s onward were generally fitted with a communal aerial system, sometimes upgraded to a full IRS (Integrated Reception System) distributing both terrestrial and satellite signals to every flat from a shared head end and, in many cases, a shared dish already aimed correctly at 28.2° east. Where an IRS exists it's almost always the neatest route for an individual flat wanting Sky or Freesat, since it avoids the near-impossible task of getting permission for an individual dish on a listed or heavily managed elevation, and the shared dish is already correctly aligned and maintained as part of the building.

Faults in these blocks tend to appear gradually rather than all at once, because a failing communal amplifier degrades slowly and the flats furthest from the head end or highest up a long vertical riser notice it first. That pattern often gets misread by residents as an issue with their own television or receiver, when testing at the head end and at several outlets along the riser usually shows the amplifier itself is the root cause. We provide a written report with actual readings for the freeholder or managing agent, since works on communal equipment normally need to be authorised and, on larger blocks, budgeted for through the service charge.

The Victorian villas set back from the main road, many converted into two or three flats, are a different job entirely: individual cabling that's often been extended flat by flat over decades, with old coax runs, unpowered splitters and outlet plates from several eras all feeding the same system. Rationalising that internal wiring — one clean feed from the aerial, a properly powered distribution amplifier, and a dedicated cable to each outlet — usually clears up multi-room faults far more reliably than replacing the aerial itself, which in most cases is still doing its job perfectly well.
