If you are loosing the strength of the signal to the channel, have you
checked it? Your box should be able to let you see the strength if you have
the channel selected when you do the test.
If it happened slowly over a period of time and the Broadcaster did not
change their output, I might think of 3 possible reasons, corrosion in your
connections, something got in the way of the signal, like a tree grew higher
(not necessarily yours), or even a weakening of your tuner.
My last HD tuner started loosing some of its' ability to receive local
channels and some satellite transponders. Replacing it solved the problem.
If you are changing your OTA antenna, you might try raising it or moving it
to another location.
