    摘要: A tracking antenna system for use in a plurality of discrete radio frequency (RF) spectrums includes a stabilized antenna support configured to direct and maintain the antenna in alignment with a communications satellite; a reflector mounted on the stabilized antenna support, the reflector reflecting radio waves along a first RF path; a first feed for gathering radio waves within a first of the discrete RF spectrums traveling from the reflector; a sub-reflector movable between first and second positions, the first position outside the first RF path and the second position in the first RF path to redirect radio waves traveling from the reflector along the first RF path to a second RF path; a second feed for gathering radio waves within a second of the discrete RF spectrums redirected along the second RF path; and an actuator for moving the sub-reflector between the first and second positions.
