Why do we use Terrestrial? Surely it would be better to move to satelite only for all channels. It must be cheaper to have a couple of satelites (1 for backup) than to have a network of huge transmitters everywere. A minidish looks much better than some array up a pole and it may be possible to have even smaller mini-mini-dishes. Surely nearly 100% of the population could be served by 2 satelite positions (one east and one west) served by high power satelites. What an opportunity to go Hi-def. Forget Sky, just 10 or so high quality channels that people really want. OK it is just a dream, but what do you think?
