I have a 10ft unimesh dish that I am having problems with. I am sure it is a simple thing but as I am new at this the fix escapes me. As I drive the dish west the elevation to the arc drops. I can correct it by adjusting the elevation of the dish up as I move form east to west. I assume that the dish needs to be turned east or west to correct this problem. Based on the fact that I have to adjust the elevation up as it goes west I am sure some one will have a suggestion as to direction I need to move the mount. Or what ever.
