As Paul Harvey would say, now for the rest of the story. This should be a final posting unless someone has questions.
After becoming convinced that the LNB was bad, I ordered a new one from Amazon. It came yesterday. This morning, I got everything out here at home and set it up just as I would when off in my 5th wheel.
Here is what I found. 1. The LNB that I had was good and so is the new one. 2. My dish arm was slightly bent downward, too little to see or measure comparing to my house SL3 dish.
I started out making sure the mast was plumb. This appears to be very critical. Then using the AAS, I zeroed in on the 101 with a 95 signal. With the dish tilted 70 degrees (for home) I discovered that I had nothing on the 99 or 103. In trying different things, I discovered that if I tilted the dish back up to 90 (no tilt) I had a weak signal on both the 99 and 103. But, if I tilted it to 70, where it should be, I got nothing. I then tilted it back to 70. At this point, I slipped the LNB out of the arm so that I could move it around by hand. What I found was I could move the LNB up, higher than the arm, and get a good signal on both the 99 and 103. Then, I got myself where I could pull up on the arm as much as I could. I couldn't tell that it moved but it must have. After that, I found that I was now getting the 99 and 103 signals in the mid 80's and still getting 95 on the 101.
So, no problems with the LNB or coax. I was using the same ones today that I was using last week. It was a dish problem all along. I plan to be a lot more careful with my dish putting it and and taking it out of my 5er. I plan to make sure it is as secure as possible while driving. When in the 5er, I plan to keep the LNB and my tripod mast off of the dish.
One thing else I found out last week. I did get the dish to work with very weak signals on both the 99 and 103. The signals on both were in the 20's and 30's. What I found was if the sky was very clear, I could see most everything. But, any clouds could make things much worse. It is much better to start out with good signal numbers. That way if it clouds up or rains, you can still be watching TV.
Thanks for all the help and suggestions.
