Mendip (Somerset, England) Full Freeview transmitter

I live in Stonehouse No7 GL10 3QP and have a new roof top wide band aerial pointing at the Mendip transmitter but have bad signal quality on all the HD channels.
Using my TV signal information I get;
Ch Sig Quality BER
32 94% 100% 0
33 92% 76% 0
34 92% 50% 0
35* 92% 40% 1268
36 92% 48% 0
37 0% 0% 2,000
48 100% 100% 0
55 96% 0% 2,000

I get a slightly better HD pictures if I tune into Wales, but cannot move C5HD & C5HD to 104 & 105;
Ch Sig Quality BER
47 93% 70% 0

Should I change the aerial to Group B to try and get some more gain in signal strength? Other thoughts?

Chris.SE & StevensOnln1: Thanks for your comments regarding quality problems on HD channels on channel 35.

My current set-up is a new wide-band aerial fitted about 2 meters higher than my chimney. The cable goes to the attic where there is an Wolsey LTE WFAV425 powered slitter feeding 3 TV's. It has a variable gain pot and I have tried different settings without any improvement. So did the guy who installed the aerial. At the time channel 35 was so bad the TV's tuned themselves to Wales HD, which was fine (although sometimes had picture breakup), until I re-tuned to get GBNEWS and now they they have gone back to channel 35.

I guess I could re-tune and pull the aerial connector out when it gets to channel 35 and put it back in at channel 36, but that's going to be a bit hit and miss...

All RG6 coax cables are new and of good quality as are the F-connectors.

If I connect my main TV directly to the aerial, I get the following results;
Ch Sig Qty BER
32 30 100 0
33 18 60 0
34 14 50 0
35 no signal
36 10 13 0
37 no signal
48 50 100 0
55 26 100 0

There are no HDMI cables connected on any of the TV's

To me the problem seems more related to weather conditions more than internal interference as sometimes everything works fine. I have turned of my broadband router that is also situated in the attic, just in case... along with everything else I can think of but no improvement...

Turning the aerial to Ridge Hill is an option, but the aerial guy said the signal wasn't any better in that direction. Unfortunately his signal box couldn't measure channel 35! Anyway I prefer HTV West news.

Any other thoughts of what I might try given this additional information??
