ABSTRACT:
A feedhorn for a satellite dish which is far more efficient picking up the transmitted microwave signal from a satellite so as to permit the satellite dish to be substantially decreased in physical size. The feedhorn is constructed to pick up either the C-Band or the Ku-Band, each in either the horizontally polarized mode or the vertically polarized mode. The feedhorn utilizes dipoles for picking up the microwave signal which are then transmitted by a coaxial cable to a printed circuit board assembly. The received signal from the printed circuit board assembly is then transmitted through a receiver. The selection of the particular band of frequency that is to be transmitted from the feedhorn and the selection of the horizontal mode or the vertical mode is to be accomplished by a remote actuator such as is commonly used with a conventional television receiver.
