Abstract
A full-wave loop antenna assembly having unique mechanical stability and electromagnetic characteristics is disclosed. The antenna assembly is suitable for use in the High frequency and Very high frequency portions of the electromagnetic spectrum and is capable of supporting multiple driven and parasitic elements in a variety of configurations for multi-band operation. The assembly includes an upper load-bearing boom and a lower boom which may be load bearing, between which at least a part of the weight loads created by the driven and parasitic elements may be distributed. The assembly may also include a parasitic element, tuned as a reflector, which is considerably longer than other parasitic reflectors which are used with antennas of this type, thereby providing the desired directional characteristics over a wider range of frequencies than are obtained by other antennas of its type.
