A study was made of a unique feed system which was developed to improve the performance of typical half-wave vertical mobile communications antennas. Popular misconceptions concerning the absolute gain of such radiators are discussed. Since vehicular roof-sized ground planes limit the realizable gain of currently used half-wave whips, the goal selected was to decouple the radiator from these undersized ground planes. The Hypcle antenna which evolved is demonstrated to have adjustable input impedance which is easily matched, true half-wave dipole performance, and minimum gain and pattern degradation.
