I have a 622 in the family room with an hd plasma and OTA antenna. I have a 508 in the master bedroom with an old crt tv. We watch basically an OTA station for a short time each late evening, but sometimes like to have satellite there. I want to get another LCD or plasma tv or display, and thought I could use TV2 on the 622 over the air, but it seems to need to be hard wired. Suggestions would be appreciated. Thank you.
