Shure UA221DB-RSMA Dual Band Passive Antenna Splitter with Reverse SMA Connections

The Shure UA221DB-RSMA is a passive antenna splitter designed for professional wireless audio systems. It features reverse SMA (RSMA) connectors and operates across both 2.4GHz and 5.8GHz frequency bands, making it a versatile component for managing antenna signals in dual-band wireless setups. This device allows a single antenna to feed multiple receivers, reducing clutter and simplifying system configuration in live sound, broadcasting, and installed audio environments. The splitter's passive design means it requires no external power, ensuring reliable operation without additional cabling or power supplies. It is specifically engineered for compatibility with Shure's GLX-D+ dual-band wireless systems and works with UA8-2.4-5.8 omnidirectional antennas as well as PA805-RSMA directional antennas. The unit is backward compatible with previous GLX-D systems, providing an upgrade path for existing users while maintaining support for legacy equipment. Its robust construction ensures stable signal distribution with minimal insertion loss. This splitter is ideal for musicians, sound engineers, and AV technicians who need to expand their wireless microphone or in-ear monitoring systems without adding multiple antennas. It's particularly useful in venues where antenna placement is limited or where multiple receivers are rack-mounted together. By consolidating antenna inputs, it helps maintain clean signal paths and reduces potential interference, making it a practical addition to any professional audio toolkit where reliable wireless performance is essential.
