Abstract
A multiple-feed antenna system includes a first feed configured to communicate signals in a first frequency range of a plurality of frequency ranges and a second feed configured to communicate signals in a second frequency range of the plurality of frequency ranges. A subreflector assembly is configured to move among multiple positions that include a first position and a second position. When the subreflector assembly is in the first position, a first element of the subreflector assembly redirects a signal reflected by a primary reflector to the first feed. When the subreflector assembly is in the second position, a second element of the subreflector assembly redirects the signal reflected by the primary reflector to the second feed.
