Abstract
This invention is a compact and cost effective signal receiver for use in conjunction with a parabolic reflector to receive electromagnetic signals from two satellites. The signal receiver has a dual elliptical corrugated feed horn to increase C/N ratio and reduce the spill over loss of the energy of signals receiving from two satellites, and to provide a sufficient rejection for preventing interference coming from the other satellite.
