ABSTRACT OF THE DISCLOSURE An antenna system having a main reflector, a sub- reflector, and a plurality of horns for radiating different frequencies includes a beam waveguide system which cancels cross polarization otherwise inherent in the system. The beam waveguide system can be used with a rotationally symmetric and stationary sub-reflector by being positioned to reflect said beam on the axis of the main reflector. Either the horns or the focusing reflectors may be rotat- ably switched, the other group being stationary.
