Is the transmitter output the same in all directions?

Of course, the COM are co-channel with the COM channels. So if there are spots where Divis' COMs come in then that could degrade of Darvel's COMs.

The COM channels carry ITV3, Pick TV, Dave, Film4, 4seven and others.

Perhaps in some cases a different would be better at rejecting these unwanted signals.

The ATV site provides some useful information.

I'm not sure what else I can add as I'm not an installer, more a technical bod.

Perhaps one of the pros can offer some more guidance.

I've checked for the above but can't find any.
My BBC 1 & 2 are constantly breaking up, freezing & showing a message saying there's no . All other channels seem fine.
My local transmitter is .

William C Small: There is no known reason for you having lost from Darvels COM4 , have you as yet checked with any of your neighbours to find out if they are still able to receive ITV3 etc? if however they can, then remove the from your TV or box and carry out an auto-tune to blank out anything stored, this then being followed by reconnecting the aerial and carrying out a second auto-tune to reload the into the tuners memory.
