Diversity Fin and 4-Channel RF + DC Antenna Distributor Bundle Pack


RF Venue Diversity Fin Antenna

The Diversity Fin Antenna is the flagship RF Venue wireless microphone antenna; it's portable, simple to operate, and capable of pushing diversity microphone systems to the limits of their performance while excelling in tough RF environments.

The Diversity Fin reduces microphone drop-outs and interference in a novel and remarkably simple way; instead of using two antennas of the same orientation spaced a distance apart, as with standard whip or paired LPDA "shark fin" antennas, it includes one element that captures vertically polarized waves, and another that captures horizontally polarized waves.  To use, just connect both the A and B ports on any antenna distributor or wireless microphone receiver and point toward the stage.  The result is an antenna that dramatically improves diversity system performance in the space of only one LPDA.

The RF + DC Distributor provides RF and DC power to 4 wireless microphone systems of any brand - allowing you to split 2 incoming antenna signals across multiple receivers.

For wireless microphone systems larger than 4 channels, multiple RF/DC Distributors can be cascaded together or configured separately with RF Venue's 2 x 1 passive splitter accessory. This high-quality yet cost-effective antenna distribution unit features a 2000 mA internal power supply [no wall wart] and amplifies the split antenna signals prior to distribution. The system comes with all of the RF and DC power jumpers needed to connect a 4-channel wireless microphone system.

RF Venue also supplies high-quality Made in USA coaxial cabling [all types and terminations], as well as splitters and attenuators, and specializes in fast turnaround on custom assemblies to meet your project requirements - including LMR400 Plenum rated cabling and standard RG8X type coax.
