The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

John: Your loft aerial may turn out to be sufficient. If it's not bothering you, you may as well wait the few months to see how it turns out. If analogue pictures are clear, not fuzzy or ghosting, it'll probably be OK, at least for the public-service multiplexes.

If it's an older model, it may be a Group B type, which works for a specific range of frequencies (C35 to C53). The public-service multiplexes will be within this range, but the commercial multiplexes will be outside it. For loft aerials, it's recommended to stick to a grouped aerial as they give more gain for a given size. A semi-wideband Group E will cover both PSB and COM multiplexes.

You will nearly always get better results from an externally-mounted aerial, as the signal doesn't travel well through walls.

I have two tv's with freeview boxes. Both only receive bbc1 and bbc2 and nothing else. Could this be an aerial or junction box problem. The TV people have been out and said it's because of low strenght from Sudbury but other properties in the area still receive all their freeview channels.

W Butcher: power is indeed increased and transmissions generally move to better channels that should be less prone to interference.

Performance is still expected to be variable after switchover completes. Digital UK are predicting that the Dover transmitter may be more reliable at this location.

Chris: Digital UK currently shows that you're out of coverage, but predicts that you should get good results on the public service channels from switchover in July. Commercial channels will initially be poor and will be variable from mid-2012.
