ABSTRACT:
A system10that includes a first satellite14at a first orbital slot B includes a first transponder32generating a first downlink signal at a first frequency and a second downlink signal at a second frequency. An outdoor unit50is directed toward the first satellite14. The outdoor unit includes a support structure80and a reflector64coupled to the support structure80and reflecting the first downlink signal from a first satellite. A first reflector reflects the second downlink signal from the first satellite. A first feed66is coupled to the support structure and receives the first downlink signal. A reflector72having frequency selective surface74coupled to the support structure80reflects the second downlink signal and passes the first downlink signal therethrough. The second feed70B is coupled to the support structure80and receives the second downlink signal reflected from the frequency selective surface74.
