Shure UA400B — UHF Replacement Antenna
UA400B Overview
The Shure UA400B is a UHF antenna engineered as a direct replacement for antennas used across a broad range of current and legacy Shure wireless receiver systems. It is compatible with current models including the PSM300, SLX4D, SLXD4D, and BLX4R, as well as discontinued receivers such as the SLX4, SLX4L, U4D, U4S, and UC4. This makes it a practical solution for facilities and touring operations maintaining older Shure wireless infrastructure alongside current systems. Audio engineers, system integrators, and houses of worship relying on Shure wireless platforms will find the UA400B a reliable service and maintenance component.
The UA400B provides a straightforward path to restoring antenna performance on receivers where the original antenna has been damaged or lost, minimizing system downtime.
