Abstract

A transmission and reception spot beam antenna is provided. A first transponder is configured to receive communications signals within a first receive spot beam and to transmit the communications signals within a first transmit spot beam. A second transponder is configured to receive reach-back signals within a second receive spot beam and to process the reach-back signals. A link between the second transponder and the first transponder passes the reach-back signals to the first transponder for transmission within the first transmit spot beam. A third transponder is configured to receive communications signals within a third receive spot beam and to transmit the communications signals within a third transmit spot beam. A link between the first transponder and the third transponder passes the communications signals to the third transponder, wherein the third transponder is configured to process the communications signals for transmission within the third transmit spot beam.
