ABSTRACT:
An omni-directional antenna is provided which comprises: 1) a first prolate spheroid having an electrically conductive first outer surface and a first center axis, 2) a second prolate spheroid having an electrically conductive second outer surface and a second center axis, 3) a structural member for supporting the first prolate spheroid a fixed distance from the second prolate spheroid so that the first and second center axes are coincident, 4) a first resistive ring mounted to the surface of the first prolate spheroid; 5) a second resistive ring mounted to the surface of the second prolate spheroid; and 5) a coaxial cable having an outer conductor electrically connected to the second surface of the second prolate spheroid and a center conductor electrically connected to the first surface of the first prolate spheroid.
