Shure UA844SWB UHF
Four-Way Active Antenna Splitter
Wideband UHF (470-952 MHz) Four-Way Active Antenna Splitter and Power Distribution System, external power supply. For ULX and SLX receivers.
The Shure Model UA844 is a UHF antenna distribution system that allows 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 outlets. A single
UA844 system can support up to four wireless receivers. A maximum of five
systems may be used with a two-tiered configuration (see user guide).
