Shure UA844 Overview
The 470 to 960 MHz Shure 2 x UA844+SWB UHF Antenna Distribution Systems with Active Directional Antennas Kit is for 6 to 9 wireless receiver systems. It includes two Shure UA844+SWB UHF wideband antenna distribution systems, two PS45 power supplies, eight locking DC power cables for the ULX4D and ULXP4 receivers, eight non-locking DC power cables for QLXD4, SLX4, and BLX4R receivers, twenty 22" BNC cables, four 6' BNC cables, four bulkhead adapters, two rackmount hardware kits, and two UA874 active directional antennas (additional BNC cables are sold separately). This kit is compatible with the Shure BLX4R, SLX, ULX-S, ULX-P, QLX-D, and ULX-D single wireless microphone systems and can be used to split one pair of antennas to multiple receivers. In addition, this system amplifies the RF signal to compensate for insertion loss. Use a Shure UA221 (sold separately) for up to 10 systems.
Note:
Set the UA874US amplifiers to -6 dB.
Shure UA844+SWB UHF Wideband Antenna Distribution System (470 to 960 MHz)
The UA844+SWB UHF Wideband Antenna Distribution System from Shure is for the expansion of a Shure wireless microphone system. It can be used to split one pair of antennas to multiple receivers and amplify the RF signal to compensate for the insertion loss.
A single UA844+ system can support up to five wireless receivers. A maximum of five UA844+ systems may be used in a two-tiered configuration. The system is compatible with the Shure QLX-D, ULX, ULX-D, SLX, and BLX4R wireless receivers.

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
