[QUOTE="archive10, post: 1000801"] [FONT=Arial] Excellent - this explains everything. Thanks for posting! You are not. Exactly my thoughts (but only gotten to a computer with decent keyboard now). OP need to observe that the dish is a mirror, both horizontally and vertically. If the non-blue LNB is pointing at 1W, then the blue is pointing at, say 14W. (No wonder OP can't see 13E.) Based on OPs photos, I strongly suggest that he repoint dish to 7E, then move LNBs to 1W and 13E respectively (as outlined in my above post). Don't try center on 1W, and then an outrigger for 13E - it's probably to far out from the center. [/FONT][FONT=Arial] No, it isn't. The curve is in the plane of the reflection from the center of the reflector. Your focus is still above the plane of the multi-LNB holder. And the 2-3 mm of the holder thickness isn't going to do much difference. I think more like 1-2 cm... But you may get away with doing what I recommend above with the center on 7E.[/FONT] [/QUOTE]
