Diversity Fin® Antenna
The RF Venue Diversity Fin Antenna is a multi-purpose polarization diversity antenna designed to be used with wireless microphone systems and other UHF receivers incorporating dual-branch diversity reception. It features a patented cross-polarized design that combines a directional log-periodic dipole array (LPDA) and a bi-directional dipole element in an orthogonal configuration to eliminate multi-path fade. By simultaneously capturing vertically and horizontally polarized waves, it achieves optimal signal constancy in challenging indoor and reflective environments.
Key Features
- Cross-Polarized Technology: Combines an LPDA antenna and a dipole antenna at a right angle within a single package.
- Dropout Elimination: Specifically engineered to capture dual polarizations, completely reducing multi-path dropouts and signal fading.
- Pro Audio Standard: Widely adopted across multiple professional audio segments for its space-saving convenience, high performance, and cost benefits.
- Dual-Branch Connection: Features two independent elements requiring two coaxial cables to feed both receiver or antenna distributor branches.
- Flexible SKU Bundles: Available in multiple configurations including a standard kit with a padded cover, or versions equipped with a black or white wall-mount bracket.
