I want to get an 811 but I don't know if I can recieve HD OTA channels where I am. I live in Lexington Ky. I looked at antennaweb.org but I want to be sure that I can receive them where I am and exactly what channels are avail.. My zip is 40517. Also if I can I don't have a clue what antenna would be the best for my location. Anyone care to try and help?
