Shure UA844+SWB UHF Wideband Antenna Distribution System (470 to 960 MHz)

The Shure UA844+SWB is an antenna distribution system that operates in the UHF band with wideband coverage from 470 to 960 MHz. It takes a single pair of remote antennas and shares the signal with as many as five Shure wireless receivers, so you can grow a multi-channel rig without adding extra antennas that clutter the stage or rack.

Inside the unit, a built-in RF amplifier keeps signal levels consistent, offering adjustable gain between -1 and +1 dB. This helps maintain reliable reception even when the antennas are installed at a distance. Standard 50 Ohm BNC connectors make it easy to tie the system into existing cabling, and the typical 30 dB of isolation between outputs reduces the risk of interaction or intermodulation between channels.

For power management, the UA844+SWB supplies 14 to 18 VDC to four connected receivers with a combined output current of up to 2.5 A. That means fewer wall warts, cleaner power distribution, and faster setup for engineers who routinely build mobile racks.

The system works seamlessly with Shure QLX-D, ULX, ULX-D, SLX, and BLX4R receivers, making it a versatile choice for rental houses, churches, corporate event teams, and touring productions that already rely on these platforms. Whether you are outfitting a small club stage or expanding a broadcast rack, the UA844+SWB delivers a simple way to add channels while keeping the RF environment stable and predictable.
