Alison: Good evening, Alison. No faults have been reported on the full Freeview at present. You are advised to see if your neighbours have lost their signals too. if they haven't, then you need to check your own installation: all leads and connections, etc. If your neighbours have lost their too, then you need to ascertain whether you share a communal aerial system with them. if you do, then you need to contact your landlord, who is responsible for ensuring that you have a tv signal in a rented home. Richard, Norwich. PS: If you have your own aerial and it is faulty, then it's your own responsibility I'm afraid. if you conclude that there is a problem on the Crystal Palace transmitter, Google "Radio & TV Investigation Service" and use the 'Contact Us' facility on the site you're taken to in order to inform the BBC that Crystal Palace needs investigating.

nicholas:

Several years ago there was a problem with of BBC2 on UHF from Crustal Palace but affecting just a few houses on one street in South . These were in Beechcroft Road, Mulgrave Road and Woodstock Road, south of Fairfield Halls that had just been built.

After much investigation by BBC and others (including the major TV rental companies) it was found that the curved copper of the Halls was causing signal bending. That meant that a small section of the roads mentioned did not get any signals at all at normal heights. The solution was to mount the aerial on each house either lower (only worked on 3 houses if I remember correctly) or much higher on very long poles with stay wires to stop the aerial from moving in the wind.

Such effects are not uncommon in areas with tall buildings or curved metal roofed buildings. When Canary Wharf was built, much of the Valley area lost TV reception as the office building blocked the signals from , so a new repeater had to be built. That's a classic example of planning rules not being very helpful to ordinary people.
