Rf Venue DFIN Diversity Fin Antenna
The Diversity Fin Antenna is a versatile solution designed for wireless microphone systems and other UHF receivers with dual branch diversity reception. It features orthogonal directional LPDA and bi-directional dipole elements, effectively eliminating multi-path fade. One element captures vertically polarized waves, while the other captures horizontally polarized waves, ensuring optimal polarization diversity reception and enhancing signal stability in indoor and reflective environments.
To use, simply connect two receiver (or antenna distributor) branches to the Diversity Fin with coaxial cables (not included). This antenna has gained popularity across various pro audio sectors due to its performance, convenience, space efficiency, and cost-effectiveness.
