[QUOTE="nelson_b, post: 621351, member: 296628"] hi - the l.n.b and holder look ok -- my l.n.b is a "pauxis" also you will need a conical feed for your C band l.n.b on your your offset dish -- like or similar to the bue one in the picture in my other post and a dielectric plate to put in the throat of the c band l.n.b for L or R circular transponders -- have you ordered these also ? are you going to get 1 metre or a 1.2 metre dish or larger ? i feel you will struggle to recieve signals on only 1 metre - it seems most C band signals are not very strong -- large dishes are normaly used i cant realy explain why c band l.n.b,s are made for prime focus dishes , but traditionaly this seems to be the case . fitting them to offset dishes is a more recent development and is more experimental -- but all my reasearch prior to recently trying out this method -- told me the same -- you have to have conical feed rings for a offset dish and you use flat feed rings for prime focus --- if not the signal reflected from the dish will not be read correctly and potential signal strength will be lost --- sorry i cant explain this better -- perhaps someone else here on the forum will ? regards nelson.b [/QUOTE]
