Are you sure? I have an OTA hooked to a 522 and get fine reception. Simply put the OTA cable to the ANT IN jack on tv 1 on the back of the 522 and done. I just tune my tv to whatever channel I want with the box off and I get OTA. Did I miss something in the message? Not being a wise guy ( I don't know enough to be a wise guy) but just trying to give back a little help. Maybe I didn't get the question right.
