Shure UA844+SWB Super-Wideband Antenna Power Distribution System

The Shure UA844+SWB is a wideband 1×5 antenna distribution system — the rack-mounted unit that lets up to 4 wireless microphone receivers share a single pair of antennas, while also distributing 12V DC power to each receiver from a single AC outlet. The "SWB" designation indicates super-wideband operation covering Shure's full UHF range.

Why antenna distribution matters in multi-channel wireless setups: Without distribution, 4 wireless receivers means 8 separate antennas hanging off the back of the rack — each receiver competing for RF in the same room, with messy wiring and compromised antenna placement. With the UA844+SWB, one pair of antennas (typically directional UA874WBs aimed at the stage) feeds all 4 receivers through the distribution unit. Cleaner installation, better RF performance, less interference, and powered receivers from a single AC outlet.

Specifications:

• 1×5 BNC active antenna distribution
• Frequency range: 470–1000 MHz (super wideband)
• Cascade input for daisy-chaining additional UA844+SWB units (up to 16 receivers)
• 12V DC power distribution to 4 connected Shure receivers
• Single-rack-space form factor
• Active RF amplification compensates for antenna cable loss
• Compatible with Shure ULX-D, QLX-D, SLX-D, BLX, GLX-D, PSM in-ear systems, and Axient Digital

Ideal for: Venues running 4+ Shure wireless channels, AV integrators specifying multi-channel wireless infrastructure, houses of worship, theaters, broadcast facilities, and any installation where multiple wireless channels need to operate reliably side-by-side.
