It's not a coverage problem that can be solved with more transmitters, it's a lack of spectrum problem i.e. Ofcom are selling it all off to the highest bidder (mobile phone companies) and not considering the benefit it would have to the UK public to keep the spectrum to expand HDTV.
Satellites don't have the same problems, and have oodles of bandwidth for HD channels. They have other benefits as well i.e 1 satellite can cover the whole of the UK rather than the cost of building & maintaining lots of transmitters. Plus they use solar panels to provide the power to transmit rather than mega watts of grid energy.

Why don't ITV and channels 4 & 5 just build their own transmitters and towers?
Simple, no?
