j.robinson: You can safely use any channel from 62 to 68, as nothing transmits in that range.

Hi Edward!
While I live in North Belfast and I get most of my channels from Divis which I would say it is about 40+ miles from your location in a different direction, I haven't found any problem with signal strength or quality. It would appear that Arqiva are currently undertaking some work on the transmitter but this work appears to effect Radio Services only. The info provided by the BBC indicates that while there is still transmission of all radio channels - some are at a weaker strength than normal.

Robert:
As you have not given a post code it is difficult to know what the receptions conditions are like in your area.
However, an aerial mounted externally at or just above roof level is always better than one in the loft. Aerials for use in a room are never very good unless you are just a mile or so from the transmitter.
Divis uses the Group A channels so the ideal aerial would either be a Group A type or a log-periodic (that covers all the channels) and should be mounted with the 'cross bars' horizontal. Do not fall for the scam of a 'digital aerial' as all TV aerials will be designed to receive the Freeview signals, some suppliers appear to charge more for the word 'digital'!
Hope that helps?
