ABSTRACT:
A High Efficiency Compact Antenna Assembly for use as a vertical antenna, used for the radiation and reception of various band length signals. The antenna assembly includes an assembly such that operation of the antenna is as efficient as antennae of much greater height. The structure of the assembly preferably includes a large surface area housing atop a conductive mast and in spaced apart electrical communication with a substantially circular collector. Spanning from the outside wall of the vertical cylinder to the mast is a minimal turn inductor so that the inductor does not create a field that would interfere with the field from the mast of the antenna. A transmitter.backslash.receiver is in connection with the antenna assembly at the mast and the collector. The mast, minimal turn inductor, and vertical cylinder are in connection with each other, while the collector interacts electrically with each.
