Shure UA221DB-RSMA — Dual Band Passive Antenna Splitter
UA221DB-RSMA Overview
The Shure UA221DB-RSMA is a passive antenna splitter engineered for use with Shure’s GLXD digital wireless ecosystem, specifically designed to support dual GLXD4R+ rack receivers sharing a single antenna pair. By splitting one incoming signal into two outgoing signals, it reduces antenna infrastructure requirements in multi-receiver installations. Compatible with the UA8-2.4-5.8 omnidirectional antennas and the PA805DB-RSMA directional antennas, it integrates cleanly into both fixed-install and touring wireless setups. This splitter is suited for system integrators, touring engineers, and houses of worship deploying GLXD4R+ receivers in shared-antenna configurations.
The RSMA connector format ensures compatibility with Shure’s current GLXD4R+ hardware, simplifying cable management and antenna distribution in rack-based wireless systems.
Key Features
