Mark: It is those who cannot receive from a full-service transmitter who will be unable to watch the Commercial channels (those that don't broadcast from the Sheriff Mountain transmitter).
The reason for this is because there are two types of broadcaster: Public Service (PSB) and Commercial (COM).
The Commercial multiplexes (each multiplex is a single signal that carries multiple services) cover about 90% of the UK population from 81 of the largest transmitters (largest by viewer population). The cost for them to broadcast from the other 1,000 or so smaller relays would roughly double their cost of transmission whilst only adding 8.5% of the population to their a potential viewerbases.
Their objective is show advertising which they sell. They want to get as many viewers as possible for lowest possible cost. Doubling the cost of transmission to increase potential reach by around 10% doesn't make sense to them. They operate purely for profit and have no obligation to provide a "Public Service".

pat, Mark: I have already answered your questions above in the posting of Wednesday 24 October 2012 10:46PM.
Unless you can receive from a full-service transmitter (which is probably only Limavady, if any) then you will only ever have PSB channels.
