RF Venue Diversity Fin Antenna
The RF Venue Diversity Fin is the shark-fin-shaped fix for dropout: instead of two identical paddles, it stacks a vertical LPDA and a horizontal dipole in one housing, so a bodypack antenna that swings off-axis still hits one polarization at full strength. Both diversity feeds come from a single stand or truss mount — one antenna to rig, two coax runs back to the distro. Passive and wideband across the post-auction UHF core, it works in front of Shure, Sennheiser, or any 50-ohm BNC distribution.

01 · What it does—and what that changes in your rig.
Product overview
Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.
The payoff
RF Antenna decisions, organized around the whole rig.
The RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. Venue DiversityA receiver with two antennas and two radio sections that continuously picks the stronger one — the difference between a dropout and a show. Fin is the shark-fin-shaped fix for dropoutA brief audio gap when the radio link fails — the thing diversity, distros, and coordination all exist to prevent.: instead of two identical paddlesA directional antenna (paddle, LPDA, helical) aimed at the stage — focuses coverage where the performers are and rejects RF from elsewhere., it stacks a vertical LPDA and a horizontal dipole in one housing, so a bodypack antenna that swings off-axis still hits one polarization at full strength.
