[QUOTE="ouagadougou, post: 284077, member: 187470"] It looks from the pic like you have a standard 40mm LNB clamp on your dish and this wont necessarily put the new feedhorn phase centre at the focal point of the dish. You arent guaranteed to get more signal just because you changed to an Andrew feedhorn especially if your original LNB has significantly better performance than the one you have used with the Andrew feed. Performance improvement due to better illumination can be very slight and is best tested with a fringe signal. Cheers. [/QUOTE]
