A:Answer There are many reasons why this could happen. If you have another TV in the house, hook up the antenna to it. If all the channels come in, the problem is with the tuner on the TV. If you have the same problem, then the antenna is not receiving the signal, or your TV is not responding to the signal properly. Since all the stations are broadcasting from the same tower, it could be that you are only getting a signal from the one highest on the tower and something, most likely a hill or big building is blocking the signal from the ones lower on the tower. It could also be that the other channels are still broadcasting VHF instead of UHF. Here's a link to an article that might help you troubleshoot the problem if these things don't help.
