Having been away from watching TV over an antenna for more than 20 years, I was surprised at what was available. When I was a kid in this area there were only 7 stations. Now all of them are broadcasting a digital signal and using that technology to send out multiple streams. I now enjoy 30-40 crystal clear channels through a tiny 12″ long antenna. I think the old 20′ wide antenna in the attic is worth more now as scrap aluminum than it cost when I was installed all those years ago.
