My dish is a 10' mesh with a ring on the back and a typical
C-band actuator. Before I added the co-rotator, I measured the dish. I measured the dish to be 119" and depth to be 20.65". The FL calculates to be 42.9". It is not warped, but it is possibly out of align. Monday I measured the FL and found it to be way off for my dish measurements. I can not get the struts to allow the feed horn to be moved that far away from the center. I set the FD at 0.36. Could I move the feed horn further out in the scalar ring to increase the FL? As best as I can measure the feed horn is in the center of the dish and is parallel to the dish. When I did this Monday my quality numbers went up an average of 15 pts across the board.
Where can I find a good, easy to understand diagram of the angles I need to check.
I certainly appreciate all of your help. This is a mystery that is baffling me. Where I live no one close by works on C-band equipment, so I am left to having to learn how to do it myself.
