      Diversity Fin® Antenna

      MAP: $649 USD

      The Diversity Fin® Antenna is a multi-purpose antenna for wireless microphones that doesn’t drop out by using our patented cross-polarized design. It provides a diversity solution in a single package by combining one log-periodic dipole array (LPDA) and one dipole antenna in an orthogonal (right angle) configuration. One element captures vertically polarized signals, and the other horizontally polarized signals.

      Key Features & Benefits

      Multi - Axis coverage Improves signal consistency in indoor reflective environments
      Two Antennas in One One Diversity Fin replaces two traditional LPDA paddle antennas
      Compatible Works with any brand wireless mic or IEM system

      About the Product

      • You only get one shot at a live performance in front of a given audience. Dropouts are disruptive and unacceptable; the Diversity Fin never drops RF signal (within line of sight)
      • Technical space can be limited and crowded; the Diversity Fin requires less effort to set up and breakdown
      • Replaces 2 "shark fin" paddle antennas at a lower cost and with better wireless performance
      • Hybrid antenna design combines 1 LPDA and 1 cross-polarized antenna
      • Works with all brands; both analog and digital
      • Padded cover provides protection without interfering with radio waves
      • Ideal for touring and install applications (although you may prefer RF Venue’s Diversity Architectural Antenna for installations)
      • Frequency Range: 470 - 698 MHz

       

       

      Product Setup

      A single Diversity Fin can supply to up to 81 wireless receivers using the DISTRO9 HDR antenna distribution system or 25 receivers by using the DISTRO4 and is available in turn-key bundles.  More setup diagrams available in the resources section.

      Most Common Questions Asked

      What is the range of the Diversity Fin?

      The range of any wireless system depends on a number of factors, of which antenna type is only one. Antenna placement, noise floor, and interfering signals are by far the most significant factors in determining range. Very few live sound applications exceed antenna to mic distances of 300’. The Diversity Fin will provide the same or slightly better range than paddle/shark fin antennas, under the same RF conditions - which is more than enough for most production scenarios. Those who need longer range should consider the CP Beam.

      How many Diversity Fins are required per receiver?

      Only one Diversity Fin is required per diversity receiver. The Diversity Fin is a polarization diversity antenna system with two antenna outputs. Simply connect output one of the Diversity Fin’s outputs to channel “A,” and the other to channel “B” on your wireless microphone receiver or antenna distributor. Consider watching the video for a better mental picture. A single Diversity Fin can accommodate four or more receivers using a single or cascaded DISTRO5 HDR antenna distributor.

      Does the Diversity Fin work with in-ear monitors?

      The Diversity Fin was designed for receive applications in a diversity receiver system. Although it is technically possible to use one of the two antenna elements (LPDA or dipole) for a transmit application, like an in-ear monitor, none of the Diversity Fin’s benefits will carry over to a transmit scheme. In other words, it defeats the point. You’re better off purchasing a single standalone paddle or a helical antenna to use with your wireless monitor.
