ABSTRACT:
A relatively low cost, easy to install and aesthetically pleasing digital video broadcast from satellite (DVBS) elliptical horn antenna designed to receive satellite television broadcast signals with circular polarity. This type antenna may be implemented as a multi-beam, multi-band antenna with closely spaced antenna feed horns operable for simultaneously receiving signals from multiple satellites that are closely spaced from the perspective of the antenna.
