Thanks for that Chris, and apologies for not providing the postcode (must learn to read before posting!) SK13 8ED. The cable is marked Triax RG6/U 19.5dB/100m (plus various other numbers) and is about a 25m run. Looking at Brian's aerial guide it looks somewhere between the class 2 and class 3 high gain types - there's 8 single horizontal elements (similar to the class 3) with the reflector having 4 horizontal bars per part as in the class 2, model unknown I'm afraid. It was professionally installed around 5 months ago and from the untrained eye seems to be solidly mounted. Checking this morning the figures for BBC1 HD are BER 500, Strength 9%, Quality 71% while such as BBC1 (non HD) show BER of 0, Strength 54%, Quality 100%

Hi Chris, thanks for the help. Yes, LCN7 in the EPG carries a local (Manchester) station. The other figures you requested are; SDN/COM4 - Strength=22%, Quality=100%, BER=0. ArqB/COM6 - Strength=8%, Quality=95-100%, BER=0 and Local mux - Strength=46%, Quality=100%, BER=0. I also re-checked BBC HD; Strength=8%, Quality=25%, BER=1400. These were all noted with this afternoons overcast/rainy skies. I did notice at the time that our aerial looked generally smaller than various neighbours who also point to Winter Hill, but the installer came highly recommended and I wasn't about to question his choice (doh!) Thanks again.

Thanks again Chris, and I'd realised what you meant with regards to the cable after I'd looked it up . The set didn't have any of the Channels carried on COM7 so I tried a manual tune for that frequency (2 in fact - 1 for the Channel number and one for the frequency, in case I'd messed up) - the set found 0 channels both times, which I assume is what you expected? I will recheck connections (the only join, which I'd forgotten about, between aerial and tv is a 2m length of Webro WF100 connected using F type connectors and a barrel).

Firstly, thank you so much for your help, it is really appreciated! There is an HDMI cable running parallel with the WF100, for around 12 inches, so I'll move that and also take the extension out of the run and re-check. Then, as you say, it's time to contact the installer. I'll let you know how it goes. Thanks again.

Hi, we had real problems with reception yesterday which I assumed was the atrocious weather. However, it led me to check signal strength on the tv which showed very low values for strength and quality. Today I've checked again (clear skies, no rain) and still find what I would think are low values. The aerial/cabling is new, pointing to Winter Hill from Glossop (we're reasonably elevated) with no splitters/joins from the aerial right through to the tv. I've tried your recommended re-tune method but wondered if you could look at the values my TV displays (these are for BBC1 HD) and comment as to whether they are within an acceptable / expected range?
Freq.-586000KHz Bandwidth-8MHz Service ID-4484 Multiplex 10720(TSID 4088, ONID 233a) Network-North West(ID302a) Bit error level(E-6) 0 BER Signal Strength 14% Signal Quality 100% Channel ID 35
sorry If this is a bit over-kill but most of it is meaningless to me! Thanks for any help.
