Does anyone have any experience with this panel antenna? I understand they are great UHF antennas. They seem to be a little more flexible than a yagi style. I'm thinking of doing an attic mount with 4 stations on the same mountain 20 miles away with 1 station in the VHF band on the same mt. My ABC affiliate is 40 miles away in the opposite direction also on the UHF band. Would this antenna work for me?
