Exclusively through B&H, this Shure Antenna and Power Distribution Package is intended for use with the Shure SLX and ULX wireless microphone systems. Choosing an antenna distribution system is often challenging, and this package is compiled to eliminate the confusion associated with wireless microphone antenna and power distribution.

Power and antenna distribution is simply a convenient and efficient way to use multiple wireless microphone systems in a single setting. The Shure UA874US distributor is capable of sending a conditioned antenna-signal (RF) to four ULX or SLX receivers, from a single pair of Shure UA874US wideband antennas. The result eliminates the need for multiple antennas and provides clear, interference-free reception. Furthermore, a single distributor will power up to four wireless receivers, eliminating bulky power cords and preserving electrical outlets for additional gear.

This package will distribute antenna signal and power to 7 Shure ULX or SLX wireless microphone systems. Included with this package are two UA844US antenna and power distributors, a pair of UA874US wideband antennas and two antenna cables. Also included are two 13-inch goosenecks, two podium flange mounts and two multi-position C clamps for permanent and mobile antenna mounting. This exclusive package is an ideal and efficient solution for running multiple Shure ULX or SLX wireless microphone systems in theaters, schools, houses-of-worship, conferences and more.

Note: Take a look at Shure's Effective Antenna Set-up Guide  for more valuable information on wireless antenna setup and distribution.

  • 2 x Shure UA844SWB Powered UHF Antenna Distribution System

    The Shure UA844SWB Wideband UHF Antenna Distribution System will effectively boost and split incoming radio-frequency (RF) signal from ULX and SLX series transmitters, and split the signal into four receivers.

    The incoming RF signal is amplified on input to compensate for insertion loss. In addition, the UA844SWB remotely powers the connected receivers via 14 to 18 VDC power outputs.

    Up to 4 UHF receivers are supported and multiple UA844SWBs can be chained until the maximum number of compatible frequencies is reached. The UA844SWB operates on the wideband UHF range of 470-952 MHz and is intended for use with the QLX-D, ULX, SLX, BLX (BLX4R only) wireless receivers.

    Supports Up to 4 Receivers
    The UA844 distributes RF signal from dual antennas. Up to 4 UHF receivers are supported and multiple UA844 can be chained.
    Provides Remote Power
    The UA844 can provide remote power to the connected receivers, eliminating bulky power supplies and access cables.
    RF Signal Boost
    Incoming RF signal is amplified before distributed to compensate for insertion loss.

    Windtech's MPC-10 Multi-Position "C" Type Clamp can be attached to a 1.25" diameter tube or any flat surface. This versatile clamp will rotate 90° in three positions. Durable and useful, this clamp has a soft rubber insert that prevents scratching of your equipment.

    Multi-Purpose
    This all-purpose C-clamp will fit both 1.25" tubes and flat surfaces and can rotate in three positions.
  • 2 x Shure UA874 Active Directional Antenna

    The Shure UA874 Active Directional Antenna uses a log periodic dipole array to offer enhanced reception when directed toward the desired coverage area. An integrated amplifier and four gain settings compensate for varying degrees of coaxial cable signal loss. The UA874 can be mounted on a microphone stand, suspended from the ceiling or mounted to a wall using the integrated swivel adapter bracket.

    Compatible with all Shure wireless receivers and antenna distribution systems that provide 12 V DC bias
    Four-position gain selector switch
    Low-noise signal amplifier that compensates for transmission loss in coaxial cable
    Integrated threaded adapter that mounts easily to microphones stands
