[[Image:40star.png]][[Image:30star.png]]* 1/4 vertical antenna type* 1/4 wave ground plane vertical omni-directional antenna type This is a good metal base antenna for being a quarter-wave antenna, however, as a quarter-wave antenna it is limited in what can be achieved in horizontal signal gain. It is a 1/4 wave ground plane with a free space gain of 2.15 dbi. Exactly the same as a unity gain dipole. The Astro Plane can best be described as a short J-Pole.
