[QUOTE="deeptho, post: 1142676, member: 215446"] The way to check if you are spot on is to slightly push (at the back) on the dish above and pull below. If the signal drops and if it also drops when you push at the bottom and pull above then you have reached dish heaven (at least until you want a bigger dish) . You can do similar tests at the arc edges, to find out which of the drawings in Michka's first post applies. In fact, it is better for the dish to point slightly too high (a fraction of a degree) in the center of the arc (1.0W) because that will lead to lower errors at the arc ends. For an 85cm dish it probably does not matter that much but on a 1.2m dish it helps noticeably. And once you are satisfied, you need to find some way to mark the current settings (paint?), or to actually measure some angles on the dish. It is not too difficult to make an inclinometer with same card board and string and obtain a result more accurate (e.g., 0.1 degree) than with a digital inclinometer. This allows you to realign if for some reason the dish moves. Also tighten all bolts as much as you can. Otherwise a big storm can undo your work. [/QUOTE]
