1. A feed assembly for a reflector antenna, comprising:
- an antenna aperture common to low, mid, and high frequency bands;
a polyrod to launch signals from the aperture in the mid and high frequency bands while supporting the low band;
a horn to launch signals from the aperture in the low frequency band;
a co-located phase center for launching signals in the low, mid, and high frequency bands; and
a low-band monopulse array located on a surface about a perimeter of the aperture to track a satellite.
