Seriously, if you're in the UK, take SullyND's advice about in which forum to post.
It's not that we aren't eager to help, but somebody in there would know which, if any, frequencies are or are not used by both cable and over the air channels where you live, which may not be the same answer it would be over here, and this would determine whether it was feasible to try to bring both in on a single co-axial cable.
