Antennas are cool! Over-the-air analog- and digital-TV broadcast signals are the best-looking broadcast signals that I have going into my home theater system. Digital satellite can be good from time to time, but cable? Forget about it! The only problem with over-the-air signals is that the science of installing and picking antennas for good TV reception is all but lost. We haven't had any reason to put up antennas until digital TV came along, except for maybe the pure pleasure of telling your cable company to take a hike.
