Shure UA221DB-RSMA RSMA Dual Band Passive Antenna Splitter for GLXD4R+ Receivers

Simplify RF routing and reduce hardware overhead by sharing a single antenna pair between two receivers. The Shure UA221DB-RSMA RSMA Dual Band Passive Antenna Splitter is designed specifically to let two GLXD4R+ receivers operate from one antenna pair, delivering reliable RF monitoring without extra cabling or powered components. Its dual-band passive design supports common 2.4 GHz and 5.8 GHz wireless audio bands and pairs seamlessly with UA8-2.4-5.8 omnidirectional antennas or PA805DB-RSMA directional antennas. Because it’s passive and uses RSMA connectors, setup is fast and maintenance is minimal — no power supply or configuration required. The UA221DB-RSMA is a practical choice for security and surveillance audio installations, event monitoring, and AV networking where space, cost, and dependable receiver performance are priorities. Reduce rack clutter, streamline deployments, and improve RF coordination across receivers. Add the Shure UA221DB-RSMA to your system for cleaner installs and more efficient monitoring — ideal for security, surveillance and live audio applications.
