Abstract
A fin-type planar antenna and a deployable dipole antenna are combined into a system as a diversity fin antenna to reduce or eliminate cross polarization fades and dropouts common to wireless audio systems used in theatres, churches and convention centers. A dual feedline connects the diversity fin antenna system to a diversity-equipped receiver in a convenient and rapid manner. The antenna system features broad bandwidth, resistance to deep nulls or fades caused by cross polarization, and an air space dielectric covering provides resistance to detuning in the presence of rain, or touching objects.
