ABSTRACT:
An omnidirectional circularly-polarized antenna system includes a plurality of dipoles equally spaced in a horizontal circle about a metal support mast. The dipoles are tilted at an angle with respect to the plane of the horizontal circle to excite circularly-polarized waves. The dipoles are fed in phase rotation with adjacent dipoles 90.degree. out of phase.
