Shure UA400B 1/4 Wave UHF Antenna for Wireless Receivers (470-752 MHz)
Product Overview
The Shure UA400B is a 1/4 wave omnidirectional UHF replacement antenna covering 470 to 752 MHz, designed for use with Shure SLX4, SLX4L, U4S, U4D, and UC4 wireless receivers. It connects directly to the BNC antenna port on compatible receivers and provides standard omnidirectional RF coverage for commercial wireless installations where a direct-mount or remote-mount antenna is required in the 470–752 MHz frequency range.
Product Description
The UA400B covers the lower UHF band (470–752 MHz) used by Shure SLX and select ULX-series wireless receivers, distinguishing it from the UA400 which covers the higher 774–862 MHz range. AV integrators specifying or maintaining wireless systems in the lower UHF band should confirm receiver frequency range before ordering to ensure the correct antenna model is selected. The UA400B’s BNC connector mates directly with receiver antenna ports and is compatible with standard BNC coaxial extension cables for remote antenna placement when the receiver is rack-mounted and line-of-sight positioning requires the antenna to be repositioned on a wall, ceiling, or equipment stand. It can be paired with the Shure UA505 remote antenna bracket (sold separately) for clean off-rack mounting.
