Audio Technica DFIN, Diversity Fin Antenna

Audio Technica DFIN, Diversity Fin Antenna

The Audio Technica DFIN antenna is a multi-purpose antenna from RF Venue. Audio Technica DFIN antenna is designed to be used with wireless microphone systems and other HF 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 of the Audio Technica DFIN captures veritically polarized waves, and other horizontally polarized waves-achieving optimal polarization diversity reception and improving signal constancy in indoor and reflective environments.

To use the Audio Technica DFIN antenna, first, you just connect both the A and B outputs to any antenna distributor or wireless microphone receiver and point toward the stage.

The Audio Technica DFIN has found widespread adoption across multiple pro audio segments for its performance, convenience, space, and cost benefits. From high-profile live sound events, to film and TV productions, to routine installations in schools and churches, the Diversity Fin is the ideal all-purpose external antenna for diversity microphone systems of any brand.

Audio Technica DFIN is designed for temporary installation or tour sound use, the DFIN includes a padded protective cover and a threaded mounting block that attaches to mic and lighting stands (mounts to ¼"-20, ⅜"-16 or ⅝"-27 threads).
