I am thinking about getting a HR20 but I am a little worried about the new dish. I heard the dish is bigger and heavier than the old oval dish. Right now, my dish is bolted to the eave (barely). I wonder how the new dish would be installed? Don't really want it bolted into the roof or on a pole (pole before the roof, certainly). Also, people seem to be getting a deal where it only cost them $99 or less but what about running new lines to the receivers? I have an antenna in my attic (uses a diplexer) and would need a separate line ran to at least one of the receivers.
