I've heard if the box has been activated before, then it should work. I've also heard that the box has to be currently active to still work with OTA. My best bet would be to see if an Ebayer is selling a box that is still active and is confirmed by them to get OTA. Don't get one of those who says "Oh yeah, I think it does OTA but I can't test it." If they cannot simply hook the box up for a minute or two and check it, then they don't really care.
