I have been doing a triple Western Satellite Dish Network (110, 119, 129 degrees) tripod setup since 2009. I have learned a lot over the years about the Dish system and its quirks.
If you are having a lot of problems, eliminate as many of the cables and connections in your antenna to receiver feed (temporarily) until you have worked out the bugs. I recently had a weird problem with the 2nd tuner signal being low (1st tuner OK) which I tracked down to bad frequency bandwidth in the cable from the dish to the trailer. Swapping out that cable fixed things. At one point in that troubleshooting I ran the cable from the antenna through a window and directly connected it to the receiver separator device, bypassing all of the trailer wiring.
When I first set up, I get the tripod positioned, level, and weighted down. I check/set the skew on the dish. Since I don't travel far, elevation should be good enough from the last use to get satellites. I use a digital compass to figure the approximate aiming angle, and then set up the dish pointing about 20 degrees EAST of that azimuth. I have the receiver on the aiming screen, with it set to the 119 degree satellite, transponder 21 (21 is usually the strongest signal on all 3 satellites). I then connect a satellite meter at the dish in line with the coax to the receiver. I swing the dish West slowly watching the meter. You will see 1 large signal peak (the 110 satellite), then a 2nd smaller signal peak. That 2nd peak should be the 119 satellite. Try slightly pulling the dish up-down to see if you get a stronger signal with an elevation change. Adjust the elevation, if needed. I know it is extra work, but once I think I have the azimuth aim right, I remove the satellite meter from the cable, as it seems to prevent the LMB switching signals from the receiver from getting to the LMB switch. Go inside and see if you have a green bar on the 119 satellite. Wait at least 15 seconds between switching satellites, or any aiming changes before looking for a result on the aiming screen. Hopefully you have the correct satellite signal and good signal strength on all 3 satellites on the aiming screen. If you have the same satellite shown being received on all 3 LMB's, DO NOT MOVE THE DISH AIMING, but reboot the receiver. Many times the reboot will bring up the correct 3 signals from what was wrong before the reboot. Be sure to secure the aiming bolts before finishing up. If you have the 110 on the 119 LMB then you need to move the dish West to the next aiming peak. If you have the 129 satellite on the 119 LMB, then you need to swing the dish East to the next signal peak. Trying to do aiming with the dish aiming screen alone, is about impossible in my opinion due to the signal change response time lag. The inline meter gives immediate response.
You may want to pay for Dish to send a technician out to check your set-up. Many, many RVers use dishes on tripods routinely, and the fact that they can be set down where trees and other obstacles are not in the way is a definite plus. At one RV park along I80 in Iowa that had an extensive total tree canopy, I was able to set up my dish 200 feet from the trailer outside the foliage and get a signal.
Good luck!!
