Well, coat hanger gray-hoverman antennas have a range of up to 80 miles, for receiving over-the-air digital tv signals. Seems like there should be a way to utilize the antenna with a tuner, mythtv and mesh networks to move forward? Mythtv is still pretty geeky, but the tuner is the stumble for me. I read somewhere that next year might have affordable units. Anybody up on that side of things?
