Hi dgates: what info Rainman is right on for checking you're alinement of the dish. but if you're dish has been set up in the past, an has worked great back then, an you have not moved none of the adjustments it still sud be right on the arc, but things will rust out or the mounts may become louse due to age of it. an a real good way to find this out is drive the dish to where it is straight up in the air (like a bird bath) then go out to the lower edge of the dish an lift up, an pull to the right an left to see if you have any movement either way. an if their is try to fix it or tighten up the bolt or bolts. now in some cases if a dish was moved alot in the past, you're pivot points of the dish will get wore out an cause this type of problem. an if all is a-ok on dish being tight, then you will need to go over the alinement just like Rainman said. good luck dgates an hope you find the problem.
