In the UK, all channels are typically transmitted from all transmitters (with some regional programming on some channels) and except for some locations where there's too much spectrum overlap and some channels are missing. Right now, they're in transition to digital (DVB-T) so that's probably not quite true anymore, as some transmitters don't have analog channels anymore. Transmitters are usually also too far apart to be able to receive a good enough signal from more than one.
