No amplifiers. As I mentioned all new cable with new compression connectors. Signal strength goes up & down from 7 to 10, SNR goes also goes up & down from 27.0 dB to 32.0 dB. Have not tried lowering antenna, I'll do that next. Lots of big trees but no buildings in LOS. When my pixelation occurs there is no loss of audio. I have and still do suspect some kind of stray RF but I can't understand why it would only affect channel 48. I've got a CB'er down the street but I've used my scanner to monitor the CB channels and it's not coming from there. Thanks for the replies. I'll update after lowering antenna 12 inches or so.
