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?
