MODEL UA844SWB ANTENNA DISTRIBUTION SYSTEM
The Shure Model UA844SWB is a UHF antenna distribution sys-
tem 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 split-
ting signal power to multiple outputs. A single UA844SWB system
can support up to four wireless receivers. A maximum of five
UA844SWB systems may be used in a two-tiered configuration.
Refer to the illustration on page 11.
