Good article, like others I have read along these lines. Some people still don't know you can get HD over the air. However, every writer fails to talk about the issue of signal reception. Just because you got a channel in Analog, doesn't mean you'll get it in Digital, and as you know, that means "no signal". I live in a major market (Dallas) and always received NBC with geat clarity until the digital switchover. Now, I seldom get NBC. Too bad this issue was not thought through before the change. And, it's not my antenna. It's most likely "multi-pathing" caused by buildings that were previously not a factor for analog TV. There's no good solution except to purchase cable or satellite.
