A quick update on my situation. Our aerial installer has now replaced the group 'A' aerial with a new Log Periodic and even tried boosting the signal which put the other frequencies over spec.
However, it hasn't made one tat worth of difference - still unable to get COM7 & COM8. The installer tells me he has fitted eight aerials in our area since the re-tune last week and has had no success at any of the other properties either.
Using his meters he says on paper we should be able to get the channels although power is down at around 40% and yet we can't.
Nothing we can do until/or unless the transmitter power is boosted.
What does the DTG reception predictor (detailed view) say about COM 7/8 at your postcode and house number ? It may be co-channel interference especially if Fenton and Sutton Coldfield are both roughly in the same direction.

All channels are green solid circles on the predictor Graham, though regarding the 19 channels that have been moved to COM7 & 8 there is an icon against each one indicating we may need a 'wideband aerial' in some instances.
Regarding any cross-channel interference. The installer tried two different aerials and pointed one to SC the other to Fenton - made no difference. He also fitted a temporary attenuator and a temporary booster - again no difference.
The installers have said they along with other colleagues from different firms have been emailing Digital UK about this issue but as yet they are not getting any feedback. One of the chaps told me they are having similar issues off Winter Hill.
In fairness they spent almost 2 hours on the job so can't complain at their thoroughness. The Log Periodic really should have done the trick but sadly hasn't.
