Before revision: In the VSAT Ku band of operation case, a typical OMT Orthomode Transducer provides a 40 dB isolation between each of the connected radio ports to the feed horn that faces the parabolic dish reflector (40 dB means that only 0.01 % of the transmitter's output power is cross-fed into the receiver's wave guide port).
