RF Venue DFIN – Diversity Fin Wireless Microphone Antenna

Product Overview

The RF Venue DFIN Diversity Fin is a patented cross-polarized UHF antenna for wireless microphone systems that provides dual A/B diversity reception from a single unit. Its orthogonal antenna element design — combining a log-periodic dipole array (LPDA) with a dipole element oriented at 90 degrees — captures both vertically and horizontally polarized signals simultaneously, eliminating the most common cause of wireless microphone dropouts. Coverage is 120 degrees horizontal with typical range exceeding 300 feet. This is the standard stand-mount version with padded cover, suited for touring, rental, and flexible deployment.

Product Description

Traditional wireless microphone setups use two separate LPDA paddle antennas for A/B diversity reception. The Diversity Fin replaces both with a single compact unit. One LPDA element captures vertically polarized signals while a dipole element oriented at 90 degrees captures horizontally polarized signals — the two elements connect to separate A and B BNC output jacks that feed directly into a diversity receiver or antenna distribution system. This polarization diversity approach addresses the main cause of wireless microphone dropouts: signal loss when the transmitter changes orientation relative to the antenna.

The DFIN is the original stand-mount version of the Diversity Fin, shipping with a padded protective cover and a stand-mount bracket that accepts a standard microphone stand thread. The padded cover protects the antenna element from physical damage during transport, storage, and repeated setup/teardown on touring productions. A single DFIN can support up to 25 wireless receivers using the DISTRO4, or up to 81 receivers using the DISTRO9 HDR. The 120-degree horizontal coverage pattern makes it effective when positioned at stage wings or front of house, pointed directly at the performance area.

Compatible with all UHF wireless microphone receivers in the 470–698 MHz range, the DFIN works with systems from Shure, Sennheiser, Sony, Audio-Technica, and all other major manufacturers. For permanent wall-mount installations, see the DFINB (black) or DFINW (white) install versions. For complete distribution packs, see the DFINDISTRO4 (4-channel) or DFIND5 (5-channel) bundles.

Key Features

• Patented Cross-Polarized Design — LPDA and dipole elements at 90° capture both vertical and horizontal polarizations, reducing orientation-based dropouts.
• Single Antenna Replaces Two — Provides A and B diversity outputs from one unit, eliminating the need for two separate paddle antennas.
• 120° Horizontal Coverage — Directional pattern for stage-wing or FOH placement with typical range exceeding 300 feet.
• Stand-Mount with Padded Cover — Includes stand-mount bracket and padded cover for touring, rental, and flexible deployment.
• Scales to 81 Channels — A single DFIN supports up to 25 receivers (DISTRO4) or 81 receivers (DISTRO9 HDR) via cascaded distribution.
• Universal Compatibility — Works with all UHF wireless microphone receivers in the 470–698 MHz range.
• All-Band Coverage — Covers all current professional UHF wireless microphone frequency bands in the 470–698 MHz range.

Typical Applications

Suitable for:

• Touring and rental wireless microphone antenna systems
• House of worship with wireless microphone deployments

Frequently Asked Questions

What is the difference between DFIN, DFINB, and DFINW?

DFIN includes a stand-mount bracket and padded cover for touring and flexible deployment. DFINB includes a black wall-mount bracket for permanent installation in dark environments. DFINW includes a white wall-mount bracket for permanent installation in light-colored environments. All three versions contain the same antenna element with identical RF performance.

How many Diversity Fin antennas are needed per receiver?

Only one Diversity Fin is required per diversity receiver chain. Connect the DFIN's A output to the receiver's A antenna input and the B output to the receiver's B antenna input. One DFIN supports four or more receivers when used with an antenna distribution system.

Can the Diversity Fin be used as a transmit antenna for IEM systems?

The Diversity Fin is designed for receive applications only. Using it as a transmit antenna for IEM systems defeats the polarization diversity benefit. For IEM transmit, use the CP Beam, CP Architectural, or CP Stage antenna.

What is the maximum range of the Diversity Fin?

Typical range exceeds 300 feet. Actual range depends on the RF environment, transmitter power level, antenna placement, and number of competing RF signals. Very few live audio applications exceed 300 feet antenna-to-transmitter distance.
