Abstract
A satellite system 10 having a first satellite 14 at a first orbital slot B has a first transponder 32 and a second generating a first downlink signal 44B at a first frequency and a second downlink signal 44C at a second frequency. An outdoor unit is directed toward the first satellite 14 and includes a support structure, a reflector 64 coupled to the support structure and reflecting the first downlink signal and the second downlink signal. A first feed 66B is coupled to the support structure and receives the first downlink signal. A second feed 70C is concentric with the first feed 66B and is coupled to the support structure and receives the second downlink signal.
