ABSTRACT:
An antenna employs the back radiation of a crossed-dipole to illuminate a parabolic cylindrical reflector. The crossed dipole is supported by a feed network mast which simplifies the feed network and eliminates the need for other supporting structure and its electrical blockage. To form an antenna system having omni-directional radiation coverage, four of these antennas are located at the four quadrants, each covering one quadrant in the azimuth direction. The RF signal is fed through a single pole four throw switch to the selected antenna to be radiated to the desired direction.
