1. An antenna system for communicating signals having radio frequencies in a plurality of radio frequency (RF) bands, the antenna system comprising:
a support assembly;
a primary reflector that is coupled to the support assembly, wherein the primary reflector is configured to receive and reflect RF signals in the plurality of radio frequency bands, where the primary reflector does not include a central opening;
a feed assembly that is movably coupled to the support assembly;
a first feed fixedly coupled to the feed assembly, where the first feed is configured to communicate RF signals in a first frequency band of the plurality of radio frequency bands;
a second feed fixedly coupled to the feed assembly, where the second feed is configured to communicate RF signals in a second frequency band of the plurality of radio frequency bands; and
a first actuator configured to move the feed assembly from a first feed assembly position, where the first feed is positioned along a first signal path with the primary reflector, to a second feed assembly position, where the second feed is positioned along a second signal path with the primary reflector, wherein the antenna system is configured such that:
when the feed assembly is in the first feed assembly position, the second feed is not positioned to communicate RF signals in the second frequency band and
when the feed assembly is in the second feed assembly position, the first feed is not positioned to communicate RF signals in the first frequency band.
