The siamese feedhorn preferably includes a first waveguide section mated with a second waveguide section. The first waveguide section is preferably positioned at the antenna's focal point to receive signals from within the antenna's beamwidth. The second waveguide section is positioned at an offset distance from the focal point to receive signals from a satellite in a different geostationary position.
