I live in Fairstead and have had a good from for the last 10 years through the switch over, over the last couple of months the signal has got worse during some parts of the day and it has been unwatchable over xmas, the is pixilly and most just say bad signal, i have re-tuned many times and it doesn't, this is happening on all TV's in the house, i do not want to get , so if the 4g is effecting this, what can be done about it and how long will it last, the idea of the digital was to free the analoge bandwidth so we had more coice and better signal, now we are swamped with rubbish channels and cant watch the main 4

Joan: It won't. COM7 (and forthcoming COM8) multiplexes have been built on a shoestring due to their expected short lifespan of only five years. At that time frequencies might get re-jigged and might get other such as carried on COM7.
