Unstable signal
I recently connected a new OTA antenna to a TV. I scanned for stations and picked up 21 digital stations. After a few hours I turned the TV back on and was only receiving about half of them. Sometime later some of them that did not work then did and others did not - very random. As I looked at the signal strength of one that was not working at the time it changed every 2-3 seconds from 12 to 68 to 0 to 12 to 0, to 68, etc, etc. Some time later I may find all the stations working and other times none of them.
Any ideas?
