[QUOTE="Channel Hopper, post: 10715, member: 175144"] Using an LNB offset on a prime focus dish can be done but is not recommended The focal point is in the centre for obvious reasons, anything off this point has a much reduced signal and the hardware will be directly in the way of the incoming signal, reducing the efficiency of the dish by a few percent As you have three dishes now it might be worth considering putting all of them up on dedeicated satellites, with the final switching system near the receiver. You will then get the maximum signal available from each satellite. If you can take pictures of what has been donated I can probably suggest the best feed design for the dish [/QUOTE]
