Shure UA844+SWB

Overview

The Shure UA844+SWB is a UHF wideband antenna distribution system designed to extend and simplify wireless microphone setups by sharing a single pair of remote antennas across up to five Shure wireless receivers. Covering a broad frequency range from 470 to 960 MHz, it ensures compatibility with multiple Shure receiver models while maintaining consistent signal strength through its built-in RF amplifier with adjustable gain from -1 to +1 dB. This system is ideal for professional audio environments where clean, reliable RF distribution is essential.

Key features

• Wide frequency coverage from 470 to 960 MHz supports the full UHF spectrum used by Shure wireless receivers, allowing flexible deployment across various channels.
• Distributes signals from one pair of antennas to as many as five receivers without significant signal loss, reducing antenna clutter on stage or in racks.
• Integrated RF amplifier with adjustable gain helps maintain strong and stable reception even when antennas are positioned remotely.
• Four DC power outputs deliver 14 to 18 VDC with a combined current capacity of 2.5 A, minimizing the need for multiple external power supplies and streamlining setup.
• Approximately 30 dB of isolation between RF outputs reduces intermodulation and cross-talk, preserving signal integrity across multiple channels.
• Standard 50 Ohm BNC connectors ensure easy integration with existing antenna cables and infrastructure.
• Compatible with a range of Shure rack receivers including QLX-D, ULX, ULX-D, SLX, and BLX4R, making it a versatile choice for rental companies, houses of worship, corporate events, and touring productions.

Connectivity and compatibility

The UA844+SWB uses standard 50 Ohm BNC connectors for both antenna inputs and outputs, making it straightforward to connect with existing antenna cables and wireless receiver racks. Its wide frequency range and compatibility with multiple Shure receiver series ensure it fits well into diverse professional audio setups without requiring additional adapters or modifications.

Performance and reliability

By incorporating a built-in RF amplifier with adjustable gain, this system maintains consistent signal levels even when antennas are placed at a distance from receivers. The 30 dB isolation between outputs minimizes interference and intermodulation, which is critical in multi-channel wireless environments. The integrated DC power distribution reduces cable clutter and power supply needs, enhancing reliability and simplifying mobile rack configurations.

Ideal uses and environments

This antenna distribution system is well suited to professional audio applications such as live music venues, broadcast studios, corporate events, and houses of worship. It supports expanding wireless microphone setups without adding extra antennas, making it a strong choice for users who need to manage multiple channels efficiently while maintaining a clean and stable RF environment.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
