Polarized Diversity Antenna for Wireless Microphone Stability
The
RF Venue DFINB Diversity Fin is a patented, hybrid-polarization antenna that reduces signal dropouts in wireless microphone systems. Combining one directional LPDA (log-periodic dipole array) element and one bidirectional dipole element in a right-angle configuration, it captures both horizontally and vertically polarized signals. This advanced design eliminates multi-path fades and provides more consistent performance than two separate shark-fin antennas, especially in indoor and reflective environments.
RF Venue DFINB Competitive Differences
- Patented polarization diversity design improves signal reliability and reduces RF dropouts
- Combines directional LPDA and bidirectional dipole in one compact unit
- Performs the work of two antennas while saving space, setup time, and cost
- Broad frequency coverage from 470–698 MHz (UHF band)
- Compatible with any brand of wireless mic receiver using BNC connectors
- Standard mount threads support versatile positioning options
RF Venue DFINB Description
Designed for professional wireless audio setups, the
Diversity Fin™ antenna improves reception stability in even the most challenging RF environments. Whether deployed in live sound, house of worship, film production, or educational AV installs, its hybrid cross-polarized design ensures a more consistent and drop-free signal. The antenna’s dual-element architecture allows wireless receivers to maintain stronger diversity reception and minimize signal loss due to polarization shifts caused by moving performers or bouncing RF reflections.
The Diversity Fin is a drop-in upgrade from two standard paddle antennas, requiring just two coaxial cables (not included) to connect both polarization feeds to a diversity receiver or antenna distributor. Engineered for field and install flexibility, it features multiple mounting thread options and rugged, lightweight construction.
