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.

DFINB Features

  • Hybrid orthogonal antenna: 1 LPDA (directional) + 1 dipole (bidirectional)
  • Improved polarization diversity eliminates multi-path fading indoors
  • Wide 228 MHz bandwidth for full UHF compatibility (470–698 MHz)
  • Simple setup with two BNC connectors for diversity input paths
  • Compact and lightweight design (1 lb) for portable or permanent installs
  • Multiple mounting threads: 1/4"-20, 3/8"-16, 5/8"-27
  • Rugged black finish for discreet stage or venue placement
