Shure UA221 Passive Antenna Splitter and Combiner

The Shure UA221 is a passive antenna splitter and combiner that simplifies RF signal routing for Shure wireless receivers. It lets you split one antenna feed into two receivers or merge two antennas into a single feed, giving you flexible options when you need to expand a system or streamline a rack without adding extra power supplies.

The unit integrates easily with Shure UC4, SLX4, ULXS4, ULXP4, U4S, and U4D receivers, so engineers who already rely on these models can put it straight to work. Each kit includes two UA221 modules, four coaxial cables, and the mounting hardware required for fast installation in touring rigs, houses of worship, corporate AV setups, or broadcast studios.

Because the UA221 is passive, you avoid the hassle of additional power adapters. Once connected, it quietly handles antenna distribution and lets you focus on the mix instead of worrying about signal paths.
