1. An apparatus, comprising:
a first antenna of a satellite;
a second antenna of the satellite, wherein a polarization angle of the second antenna is different from a polarization angle of the first antenna;
one or more processors; and
at least one memory storing instructions that, when executed by the one or more processors, cause the apparatus to perform:
receiving, by the first antenna, a first signal;
receiving, by the second antenna, a second signal;
combining the first signal and the second signal into a single signal; and
forwarding a feeder signal from the satellite to a base station, wherein the feeder signal is based on the first signal and the second signal; wherein
the feeder signal comprises the single signal, and
wherein at least one of the feeder signal does not comprise the first signal received by the first antenna, and the feeder signal does not comprise the second signal received by the second antenna.
