I’ve been fed up with Comcast, the cable TV company, for a long time now. They have a long history of (accidentally) charging me for services I don’t have, (accidentally) removing services I pay for, and (intentionally) deleting my favorite channels from the lineup so they can move them to other levels of service that I have to pay extra for. Meanwhile, I’ve long wanted to try this “over-the-air” HD thing I’ve heard so much about. Getting HDTV for free, and all I need is an antenna? But I kept thinking that it required the equivalent of a ham radio license or something, and that all I’d get would be one or two channels. So I kept pushing that thought to a back burner. Then I got this month’s Comcast bill and I decided enough is enough.
