Will: Yes, but it was because Channel 5 had to make the network using just C35 and C37, which was many less than the nine-ish that were allocated to the other four analogue channels. The lower power levels were fully intentional.
Oddly, at some sites such as Whitehawk Hill, Channel 5 came though louder than all the analogue channels...

MickO: The "official" recommendation is that people should stop using analogue TV on these frequencies to do this sort of thing as "analogue RF" is depreciated.
Obviously there are lots of Sky boxes out there with modulators in, so in reality it will continue, but it won't be long before many places have digital TV or 4G mobile on all channels from C21-C69.

Thomas: You can't really get around the "out of group" problem when the band being allocated sits in one band, but as I said people have been officially advised to use wideband aerials since 1998.
The most recent set-top boxes are able to detect and deal with multiple-region issues much better than the "plain old" ones, so this should be less of an issue for people as old equipment is replaced.
There is no "hint" of what the multiplexes will carry, that's why there is a consultation going on - Ofcom | 600 MHz band and geographic interleaved spectrum .
Reading the documentation it seems quite clear that DVB-T2 is the most sensible use of the allocation, so this would mean about 12 HD channels.
Given your main transmitter is Bilsdale where Channel 5 is at the same power and on the same mast as the rest and in-group, it is somewhat surprising that you have had any issues with the analogue service.

Chris Miles: Thanks, yes C61 is now allocated to 4G mobile. I must have missed this reallocation.

Dave Lindsay: C36 was previously used for RADAR, and is clear in the whole of Northern Europe.
The other channels are used for TV in France, The Netherlands, RoI and other neighbouring countries and the configuration of their networks means the UK cannot use them for a SFN, apparently.
As I pointed out in the previous article, this is a shame as C37 is receivable by all groups of aerial.

ChrisW: Except that these signals are already down perhaps as much as -12dB as it is...

Mark Heselden: I think, again, "ofically", aerail groups are a legacy of analogue UHF television and there nothing to be gained (so to speak) from not using wideband aerial at all locations.

Dave Lindsay: I think you have a strange idea of "politically-driven nonsense".
