[QUOTE="sonnetpete, post: 793446, member: 310216"] For an explanation about offset angles and how to calculate them look at this : _http://www.satsig.net/pointing/finding-dish-offset-angle.htm In reality, though setting up your dish by this method should get you approximately in the right elevation, manufacturing tolerances will inevitably bring about errors. E.G. I have a small dish fixed on Hispasat at 30°W. Dishpointer tells me it should be at 27.7° elevation. When I've set the dish up using a meter to locate the strongest signal, the scale on the mount tells me the dish is at 35° elevation. I bet that, if I took a reading with an angle finder the dish face wouldn't be at the correct angle either because of the mechanical difference between the manufacturers specification and what the finished article actually turns out to be. If I were you, I'd forget about calculations and angle finders. Get your meter hooked up to the dish and adjust the dish till you achieve the best signal possible. 99% of the guys using this site do it that way. Edit : Knew I'd take too long writing that post.
