Shure UA844SWB Antenna/Power Distribution System

Current Stock:

The Shure Model UA844+ is an antenna distribution system that allows for the expansion of wireless microphone systems by splitting one pair of antennas to multiple receivers. It also amplifies RF signals to compensate for insertion loss that results from splitting signal power to multiple outputs. 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.

UA844+SWB replaces UA844SWB. Antenna Splitter and Power Distribution System for receivers, 4-way active antenna splitter plus cascade port, different frequency versions available, external power supply.
