Shure PA821B — 8-to-1 Wideband PSM Antenna Combiner
PA821B Overview
The Shure PA821B is a professional wideband antenna combiner built specifically for PSM in-ear monitor systems, supporting P3T, P9T, and P10T transmitters across the 865-960 MHz frequency range. By combining up to eight transmitter outputs into a single antenna distribution path, the PA821B significantly reduces antenna clutter and simplifies RF infrastructure in dense wireless deployments. It is well suited for touring productions, houses of worship, broadcast facilities, and large-scale live event venues running multiple PSM systems simultaneously.
The PA821B streamlines rack layouts and antenna placement logistics, making it a practical solution for system integrators and RF coordinators managing complex in-ear monitor rigs.
