Ian Jones: You should be getting avery good signal on all channels. Best guess - somethings up with your aerial system. Normally, BBC channels are the strongest, but if you've got a loose connection, frayed wire, etc, then that mux might be the one that suffers.

Hi Mike
Thanks for that but all is in order.
I have found that my friend at no:5 BS14 9AQ (I'm at 32) suffered the same problem, the total loss of all BBC channels, as did some of our neighbours. My friend actually had his ariel turned to pick up the Ilchester Crescent signal where he could get BBC but not a good signal - this has always been our problem hence Mendip.
The ariel fitter that turned my friends ariel said that there had been a lot of work on the O2 mobile mast at the junction of our road and the WEllS RD at the same time as we experienced problems.
Can you please advise and what action will be taken.
Many thanks
Ian Jones

Do you have an aerial amplifier at all?
If work on the O2 mast has meant adding 4g in the 800MHz band (haven't checked) then there may be some overload happening, you might need a filter. However I'd had expected other mux channels to be knocked out as well.
Are you talking about the HD channels or the SD ones?

Hi Chris
Yes we do have an ariel amplifier.
Do not understand 'other mux channels'.
As to HD or SD channels all I can tell you is that when I do a 'First Time Installation' I end up wit 73 channels instead of 100+. The only thing I can honestly tell you is that the is no BBC channels at all. I have the basic Freeview service.
You mention 'adding 4G in the 800MHz band (haven't checked)' - do I read this as you will check?

Ian Jones: If you think your difficulties and those of your neighbour could possibly be interference from 4G services operating in the 800MHz band then you need to contact at800. This is the organisation set-up by the mobile operators and tasked with alleviation of reception issues:

Ian Jones: If at800 do send you a filter, because it is suspected that 4G interference could be the culprit, then it must be fitted before the signal amplifier. Thus, if your amplifier is on the roof then a filter will need to be fitted up there, but not the usual plug type they usually send. You will need to raise this issue with them should it apply.
