Abstract The invention provides a Horn-type feeder unit which comprises: at least first and second waveguides in positions so as to face each other over a center line, each having an axis parallel to the center line; and first and second horns on extension lines of the axes. The outer ends of the first and second horns have aperture end faces, respectively. Each of the first and second horns are perpendicular to the travel directions of radio waves transmitted from at least two broadcasting satellites orbiting around the earth and reflected by an antenna on the ground.
