Overview
Key Features
NEW, IMPROVED PERFORMANCE - GLX-D+ Dual Band Digital Wireless offers new features previously unavailable in the first generation of GLX-D Wireless: operation in both 2.4 and 5.8GHz, improved battery life, and multiple receiver options.
EXCEPTIONAL, DIGITAL WIRELESS AUDIO - Always come through clear and captivate the audience with superior, transparent audio. GLX-D+ Dual Band intelligently avoids interference to give you total, reliable wireless freedom.
NEW DUAL BAND WIRELESS TECHNOLOGY - provides reliable and consistent signal by automatically scanning both 2.4 and 5.8GHz bands and selecting the cleanest channel. More than double the bandwidth ensures that dropouts won't stop the show.
EASY, WORRY-FREE SETUP & MANAGEMENT - Transmitters and receivers pair up automatically making setup as simple as possible. Smart frequency management continuously monitors the spectrum and moves to a clean channel in case any interference appears.
SMART RECHARGEABILITY - Up to 12 hours of runtime. The new SB904 battery can be charged directly on the receiver or via included USB-C connector on the handheld microphone or bodypack. Quick charge allows for 1.5 hours of use from a 15 minutes of charge.
RF PERFORMANCE FOR MULTIPLE SYSTEM INSTALLATIONS - GLX-D+ Dual Band provides improved RF performance, antenna distribution and automatic frequency management for up to 16 half-rack systems. Frequency Manager (GLXD+ FM) required (sold separately).
LICENSE-FREE FREQUENCY RANGE - allows you to travel without worrying about licenses, frequency coordination and other technical hurdles.
MULTIPLE SETUP OPTIONS - Available in rack-mount, tabletop and guitar pedal receiver options with a wide selection of lavalier, headset and handheld microphone choices - including the legendary SM58. Not Backwards Compatible with GLX-D or GLX-D Advanced.
WHAT'S IN THE BOX? UA8-2.4-5.8 antenna, and attaching hardware. Free 2-YEAR WARRANTY included.

Pros & Cons
👍 Pros
- Covers both 2.4 and 5.8GHz bands, giving the GLX-D+ system a vastly wider RF spectrum to navigate around interference
- Designed for multi-system deployments — supports up to 16 half-rack systems with proper distribution hardware, making it viable for theater, broadcast, and large live production rigs
- Remote placement capability improves line-of-sight and signal consistency when the receiver can't be positioned near the stage
- License-free frequency operation removes the coordination headache when traveling between venues or regions
- Ships with a two-year Shure warranty, which carries weight for touring and production professionals who depend on gear reliability
👎 Cons
- Not backwards compatible with first-generation GLX-D or GLX-D Advanced systems — existing GLX-D users cannot simply add this antenna to their current setup
- Full multi-system antenna distribution requires the separately purchased GLXD+ FM Frequency Manager, adding cost to large installations
- Sold as an antenna only — no receiver, transmitter, or cable included, which may catch buyers off guard if they're expecting a more complete RF solution
- Performance ceiling is tied to the GLX-D+ system's digital processing; users moving from professional UHF systems may notice the 2.4/5.8GHz bands are still more congested in urban environments than dedicated UHF spectrum
Frequently Asked Questions
What receiver systems is the UA8-2.4-5.8 antenna compatible with?
This antenna is designed exclusively for the GLX-D+ Dual Band system. It is not backwards compatible with original GLX-D or GLX-D Advanced receivers — if you're running the older generation, this antenna will not integrate with your setup.
How does the dual-band design of this antenna improve RF stability in crowded venues?
By supporting both 2.4 and 5.8GHz simultaneously, the antenna allows the GLX-D+ system's smart frequency management to scan across more than double the available bandwidth. In congested RF environments — convention halls, houses of worship, multi-system live stages — this wider scan range gives the system more clean channels to lock onto, reducing the likelihood of dropouts.
Can this antenna be used with antenna distribution hardware for multi-system installations?
Yes. The UA8-2.4-5.8 is designed to support RF distribution configurations with up to 16 half-rack GLX-D+ Dual Band systems. You will need the separately sold GLXD+ FM Frequency Manager to manage automatic channel coordination across that many systems.
Does this antenna require any special cabling or mounting hardware?
The antenna ships with attaching hardware. For remote antenna placement — which is often necessary to improve line-of-sight in large rooms — you'll want standard 50-ohm coaxial cable and the appropriate Shure antenna distribution components. The antenna itself uses industry-standard connectors compatible with Shure's distribution ecosystem.
Is the UA8-2.4-5.8 sold as a complete wireless system or just the antenna?
This is the antenna component only. The package includes the UA8-2.4-5.8 antenna and attaching hardware. The GLX-D+ Dual Band receivers, transmitters, and microphone capsules are sold separately.
