You can always add a shroud to all parabolic reflectors to eliminate sidelobes.

You can actually move the feed horn around quite a bit and compensate for it by re aiming the reflector. Minor loss of gain, more loss the more you deviate from boresight. And the actual boresight focal point is not a point but rather a spongy spherical balloon with its center at the focal point. If you have off boresight interference I think you might be able form some kind of shield for it.

Double bonus if theres one that allows placement of the remote transmitter and reflection points on the ground -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
