I think Randu is closest to my solution. I have same equipment I have had for last 3 years. We moved RV about 100 feet North of old position and moved satellite & tripod with it. So I had to re-align. In fact, directv said that it seems to be just the one satellite I can't zero in on. So, I guess my next question is does it make a difference which of the 4 positions on the LNB I screw the 2 coax cables into? This weekend I will try a re-alignment. Hopefully I can get it fixed. Thanks for everything folks. I appreciate all of the thoughtful responses
