Shure UA400 — UHF Replacement Antenna
UA400 Overview
The Shure UA400 is a UHF antenna engineered as a direct replacement for the standard antennas supplied with SLX4 and SLX4L wireless receivers. It is a straightforward, reliable solution for restoring or maintaining antenna performance on existing SLX4-series installations.
