RF Venue DFIN Multi-Purpose Diversity Fin Antenna For Wireless Microphones

The RF Venue Diversity Fin is a versatile antenna designed to minimize dropouts through its proprietary cross-polarized hybrid design, making it compatible with diversity wireless microphone systems across all brands. It features a mounting block with 1/4"-20, 3/8"-16, and 5/8"-27 threads, allowing secure attachment to your preferred stand. The Diversity Fin combines one LPDA and one dipole antenna in an orthogonal configuration, with one element capturing vertically polarized waves and the other horizontally polarized waves, effectively performing the same function as two shark-fin paddles. This innovative design significantly enhances RF and audio performance in high-profile live sound events, film and TV productions, as well as routine installations in schools and houses of worship.
