Abstract:
An antenna feed assembly capable of configuring communication ports of an antenna having a fixed communication waveguide in a proper polarization, wherein said assembly comprises:a common waveguide having a body extending longitudinally between first and second ends, with a first end that is capable of connection to a feedhorn of the antenna and a second end that is capable of connection to the fixed communication waveguide; an opening formed in said body at a point between said first and second ends; a first port in communication with said opening of said body and a second port in communication with said second end of said body, said first and second ports defining respective polarizations and having a predetermined difference in polarization between each other; and a rotatable coupling connected to said second end of said common waveguide and configurable for connection to the fixed communication waveguide, said coupling allowing said common waveguide to rotate with respect to the fixed communication waveguide to thereby alter the polarizations defined by said first and second ports while maintaining the predetermined difference in polarization between said first and second ports.
