Abstract: A generally paraboloidal shaped reflector with a coaxial feedline extending outwardly along the axis thereof and a disc antenna feed mounted in spaced relation from the reflector, said feed including a first disc forming a ground plane mounted coaxially on the feedline and a second disc forming a disc radiator mounted coaxially on the feedline. The center conductor of the coaxial feedline extends outwardly through the end thereof and back through an opening in the ground plane disc to a feedpoint on the disc radiator.
