MODEL UA844 ANTENNA DISTRIBUTION SYSTEM

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 outputs. A single UA844 system can support
up to four wireless receivers. Multiple UA844 systems can be used
in a tiered configuration until the maximum number of compatible
frequencies is reached.
