Audio-Technica DFIN Diversity Fin Antenna

The Diversity Fin Antenna is a multi-purpose antenna from RF Venue. It is designed to be used with wireless microphone systems and other UHF receivers incorporating diversity reception, and comprises orthogonal directional LPDA (log periodic dipole array) and bidirectional dipole elements in order to eliminate multipath fade. One element captures vertically polarized waves, and the other horizontally polarized wavesachieving optimal polarization diversity reception and improving signal constancy in indoor and reflective environments.

Key Features

• Designed to be used with wireless microphone systems and other UHF receivers incorporating diversity reception
• Incorporates both directional LPDA and bidirectional dipole elements
• Captures both horizontal and vertically polarized waves in a single unit
• Improves signal consistency in indoor and reflective environments
• Single Diversity Fin replaces two traditional LPDA antennas
• Includes a padded protective cover and a threaded mounting block that attaches to mic and lighting stands (mounts to 1/4”-20, 3/8”-16 or 5/8”-27 threads)
