Polarisation Diversity Antenna (470-698 MHz)

The patented Diversity Fin™ is a multi-purpose antenna for wireless microphones that reduces dropouts using a cross-polarised, hybrid design.

It combines one LPDA (log-periodic dipole array) and one dipole antenna in an orthogonal (right angle) configuration. One element captures vertically polarised waves, and the other horizontally polarised 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 (enure you use high quality 50Ω cable).

From high profile live sound events, to film and TV productions, to routine installations in schools and churches, Diversity Fin is the ideal all-purpose external antenna for diversity microphone systems of any brand.

Extra note:

Because DFIN (Diversity Fin) is such a unique solution, we’ve ripped the FAQ section from RF Venue’s website, and pasted it below. There’s a heap of extra information, well-worth perusing.

FROM THE SHOP FLOOR

“It rejects off-axis sounds brilliantly, so there’s no danger of other drums or instruments bleeding into the kick drum recordings. This saves a lot of time and effort during the EQ stage of the mixing process.”

Darren, Head of Technical Sales
