[QUOTE="Terryl, post: 959418, member: 369937"] The big problems with a standard "C" band dish in trying to setup multiple LNB's on it is the fact that they don't have very good side to side reception. An LNB mounted to the right or left of dead center may have signal problems, as the dishes focal area is round, (like the dish) and not elliptical, the dish would need to be shaped like a big radar dish (somewhat) to get usable signals to the side mounted LNB's, and I haven't seen one like that around for many many years. This is why most are motorized to pan left or right. Now I'm not saying that it may or may not work, you would have to test this by moving the dish ever so slightly left or right to see how far down your signal drops, take note of how far it can be moved to see how large a focal area you have with that dish, you may need to remove the Scala ring (if you can) to see this. as that is for side rejection of unwanted signals. This may be why the setup posted by Vipersan does not have one. [/QUOTE]
