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:

Contact us | Advice or general enquiries | at800

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.

Aerial on roof.

I seem to have a problem with Channel 33: All the HD channels break up and are unwatchable.

I don't know what to do first to work out what the problem is.

Anyone know of a aerial installer who knows what they are doing and won't rip you off?

Thanks

It seems to be intermittent.

BBC News channel seems to break up quite often, but I recorded 'Film review' and it recorded without a single problem, but that was for only 15 minutes though?

Anthony: Should you have two aerials - one on Mendip and one on Wenvoe - and these combine into one downlead, then this may be the cause of your issue receiving PSB1 on C49, and indeed any channel below C51 from Mendip.
