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

Hi Edward!

While I live in North Belfast and I get most of my from which I would say it is about 40+ miles from your location in a different direction, I haven't found any problem with strength or . It would appear that Arqiva are currently undertaking some work on the but this work appears to effect Radio 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 mounted externally at or just above level is always better than one in the . Aerials for use in a room are never very good unless you are just a mile or so from the .

uses the Group A 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 ' aerial' as all TV aerials will be designed to receive the signals, some suppliers appear to charge more for the word 'digital'!
that helps?
