1. A multiple-feed antenna system for communicating signals in a plurality of radio frequency (RF) ranges, the multiple-feed antenna system comprising:
a first feed configured to communicate signals in a first frequency range of a plurality of frequency ranges;
a second feed configured to communicate signals in a second frequency range of the plurality of frequency ranges; and
a rotatable mechanism configured to change a relative position of the first feed and/or a position of the second feed with respect to a reflector of the multiple-feed antenna system, the rotatable mechanism being moveable among multiple positions that include a first position and a second position, wherein:
when the rotatable mechanism is in the first position, a signal reflected by a primary reflector enters the first feed; and
when the rotatable mechanism is in the second position, the signal reflected by the primary reflector to the second feed, wherein the first feed and the second feed are positioned at positions near an outer perimeter of the primary reflector and offset from a center portion of the primary reflector, and a subreflector assembly is supported by a frame mounted on the primary reflector.
