Do you still have the antenna? If so, it will still work. Nothing magic about HD signals requiring a new antenna. So you can give it a try and see what you can tune in. Tell us what model it is and we can help you out more. So just connect to coax on the TV and start pointing. Many HDTV's have a built in signal strength indicator to help you out.

As for new technology, well, there's not much to in the way of a magic antenna.....although some will claim they are. There are still plenty of good antenna options out there and good information and reviews on them to help you out. Not that I know from experience, but after checking your plot again, I realized you don't have any VHF stations to pick up. That would mean you could go for a specific UHF only design. Maybe a Winegard HD-9095P would be a good choice for you. It's rated for 65 miles I think, and it's UHF only - very directional as well. And it won't break the bank either. A hi-gain preamp like the CM-7777 could help out if needed.

Good luck on turning that sat dish into a bird bath!
