Shure UA844+SWB-TA Wideband Antenna Distribution System (470 to 960 MHz) (TAA-Compliant)

Product Overview

The Shure UA844+SWB-TA is a wideband UHF active antenna distribution system covering 470–960 MHz, designed to expand Shure wireless microphone systems by splitting one pair of antennas across up to five wireless receivers. As a TAA-compliant unit, it qualifies for government and institutional procurement. The standard configuration includes a full cable kit — ten 22-inch BNC cables and locking DC power cords for ULXD4 receivers — providing an out-of-box deployment solution without requiring additional cable procurement.

Product Description

The UA844+SWB replaces the legacy UA844 series with active RF amplification to compensate for the insertion loss introduced by antenna splitting. A single unit provides four active receiver outputs plus a cascade port, enabling a second UA844+ to extend the configuration to a maximum of five units in a two-tier architecture — supporting up to 20 wireless receivers from a single antenna pair. The 1U rack-mount form factor with included rack hardware integrates directly into commercial AV, broadcast, and government system racks. Its 50 Ω BNC inputs and outputs maintain compatibility with standard Shure RF cabling. The 470–960 MHz frequency range covers all current Shure UHF bands, eliminating frequency-specific splitters in multi-band deployments. For the cable-light version suited to pre-wired rack environments, see also the Shure UA844+SWB/LC-TA.

Key Features

• Wideband 470–960 MHz Coverage — Spans all current Shure UHF wireless frequency bands, eliminating the need for frequency-specific distribution hardware in multi-band wireless system deployments.
• Active Antenna Splitter with RF Amplification — Four-way active splitter with built-in gain compensation maintains adequate signal level at each receiver output, preventing the signal degradation typical of passive splitting.
• Cascade Port for Multi-Tier Expansion — Dedicated cascade output connects a second UA844+ unit, supporting up to a five-unit, two-tiered configuration for large-scale multi-receiver wireless installations.
• DC Power Distribution — Four DC power output ports supply 14–18 V DC to connected receivers, simplifying rack wiring in commercial AV and broadcast installations.
• Full Cable Kit Included — Ships with ten 22-inch BNC cables, two 6-foot BNC cables, four non-locking DC cords (QLX-D, SLX-D, BLX4R), and four locking DC cords (ULX-D), providing complete connectivity for an immediate deployment.
• 1U Rack-Mount Form Factor — Standard 1U dimensions (45 x 483 x 172 mm) with included front-mounting antenna hardware and rack-mounting hardware for clean integration into commercial system racks.
• TAA-Compliant — Meets Trade Agreements Act requirements for federal, state, and local government procurement programs.

Frequently Asked Questions

How many receivers can the UA844+SWB-TA support?
A single unit supports four receivers via active RF outputs plus one cascade port. In a two-tier cascaded configuration with multiple UA844+ units, up to 20 receivers can be driven from a single antenna pair.

What is the difference between the UA844+SWB-TA and the UA844+SWB/LC-TA?
Both units are electronically identical. The UA844+SWB-TA ships with a full cable kit including ten 22-inch BNC cables and locking DC power cords for ULX-D receivers. The /LC version ships with only two 22-inch BNC cables and no locking DC cords, suited for environments with existing cable infrastructure.

Is the UA844+SWB-TA compatible with all current Shure UHF wireless systems?
Yes. The 470–960 MHz range covers all current Shure UHF wireless bands, including QLX-D, ULX-D, SLX-D, Axient Digital, and BLX-R.

Can it power active directional antennas like the Shure UA874?
Yes. Both RF input ports supply 15 V DC bias voltage (150 mA maximum each), which is compatible with active directional antennas such as the Shure UA874.

Is installation support available for government or institutional deployments?
Shure provides full technical documentation and Creation Networks offers pre-sales support for complex wireless system integration projects, including TAA-compliant procurement.
