RF Venue DFINB, Multi-purpose Diversity Fin Install Antenna (black) for wireless microphones

RF Venue DFINB Diversity Fin Antenna for Install wallmount kit Black

DIVERSITY FINPolarization Diversity Antenna

The patented Diversity Fin™ is a multi-purpose antenna for wireless microphones that reduces dropouts using a cross-polarized hybrid design. It combines one LPDA and one dipole antenna in an orthogonal (right angle) configuration. One element captures vertically polarized waves and the other horizontally polarized waves—doing the same job as two “shark fin” paddles while greatly improving RF and audio performance.

To use just connect both the A and B outputs on any antenna distributor or microphone receiver and point toward the stage.

The Diversity Fin has found widespread adoption across multiple pro audio segments for its performance convenience space and cost benefits. From high profile live sound events to film and TV productions to routine installations in schools and churches the Diversity Fin is the ideal all-purpose external antenna for diversity microphone systems of any brand.
