Here’s something I bet you didn’t know. Local television stations are broadcasting their high-definition signals over the air. With just an inexpensive HD antenna, it’s possible to get high-quality digital television with no monthly fee. And since it’s digital, you get a sharp, clear image unlike with antennas of old. This is a less expensive alternative to paying for cable or satellite broadcasts. The only downside is that you don’t get the non-local channels like HBO, CNN, etc.
