Looks like I'll have to invest in a new wide band aerial to replace my group A which is pointed at Crystal Palace. I coud live without all of the channels I will lose except for BBC 4 HD. I see a group T is recommended, I've not come across this before. I thought wide band was group W.
A group W was intended to cover all the pre DSO UHF frequencies from 21 to 68.
Post DSO with frequencies being broadcast ranging from 21 to 60 the group T was defined. Its intended range is wider than both the intended ranges for group A and B and therefore it is "wideband".
After total clearance of 700mhz the broadcast range will be 21 to 48 and aerials aimed at that range will be called group K wideband. It is "wideband" because it is wider than group A's intended range of 21 to 35, and also wider than of group B's intended range of 35 to 53, but while COM7 and COM8 are broadcasting on 55 and 56 not quite wide enough if you want to receive those while they are still available.
In practise aerials can also receive some channels outside their intended range and so it is possible that some wideband T aerials could pick up com 7 and 8, but no guarantee, especially as com 7 and com 8 are on reduced broadcast strength.
