[QUOTE="archive10, post: 974400"] That reflector looks awfully thin, and ... there's no LNB at the focal point??? Until you realise that the lnb is on th main body of the craft, and that you are looking up at the reflector from underneatth and in front of it. It's an offset reflector! Haven't seen that on a satellite before. (You are looking through the reflector at the ribbing, or whatever you call it.) Won't that take some serious alignment thrusters? ... one small jerk and you're pointin several 100 km to one side of where you where just before. Or is that just the same as a PF dish?? Can't get my head around it. [/QUOTE]
