The Shure PA421B is a professional wideband antenna combiner for Shure PSM in-ear monitoring systems. Covering 470–865 MHz, it consolidates multiple IEM transmitter outputs into a single RF feed, allowing you to run one external antenna for cleaner spectrum management and simpler rigging. By centralising RF transmission, it helps minimise intermodulation, reduce cable clutter, and improve coverage consistency across demanding stage environments. Built for touring and installation alike, the PA421B integrates neatly into standard 19-inch rack workflows and provides dependable RF performance for productions where reliability is paramount. Its robust design and wide frequency range make it a strong choice for rental houses, venues, broadcast, and live sound teams looking to streamline racks and stabilise their RF infrastructure. Ideal for applications where tidy system design and stable, consistent in‑ear monitoring are priorities.
