I think I have to call it quits.  I'm REALLY bummed about this.  My installer came back with a 190 mile antenna for my locals that are 50 miles NNE of me.  One of the channels I had, I have no more, and I now get another channel (for a total of 1 OTA channel.)  Why on earth would a 190 mile antenna not get a signal, who knows.  We have an amp hooked up, still no joy.
