A Foster: Yes, that is correct, if you want to use these services when they launch, you will need a wideband aerial.
Actually, looking at the data, you may also need a wideband aerial to receive SDN and ArqA after switchover, but as they are only "just" out of group and you are in a very strong signal area, you will probably be OK.
The official advice for the last decade or so has been that you should fit a wideband aerial if you upgrade, but there is no need to fit a replacement for access to the "public service" multiplexes.
Most transmitters also have the COM multiplexes "in group" after switchover, but not all.

David: I'm really sorry, I made a copy and paste error. It's Brougher Mountain, not Durris, that goes along with Limavady to be not part of the SFN.

Will: The correct answer is yes, it's Brougher Mountain and Limavady that won't have the SFN.

Charles Stuart: When the existing five multiplexes are converted to DVB-T2 they will use the same plan as now with DVB-T. I'm not sure why you think there would be anything "left over"?
Local television is being provided on Interleaved Frequencies - see Local TV on Freeview - new Ofcom maps | ukfree.tv - independent free digital TV advice . COM7 or COM8 could, in theory, be used for local services, COM9 can't as it's a national SFN.

ChrisW: Actually, the post you make is showing that DTV signals are effected by co-channel interference from pre-switchover analogue signals, not from a pure-digital network.

Bill: All multiplexes, other than the BBCA one, are on the same power level they have been since 2003.

Will: No, due to the border with the RoI, the UK-wide SFN cannot be broadcast from Durris or Limavady.
