Product Description
Shure PA421BX 4-Channel Antenna Combiner (865-960MHz)
Four-to-One Wideband PSM Antenna Combiner for all P3T, P9T and P10T Transmitters (470-865 MHz)
The PA821B active broadband antenna combiner streamlines the simultaneous operation of many PSM systems at a venue. The PA821B combines the RF outputs from up to four PSM transmitters into one RF output to feed a single transmit antenna. This provides significantly improved reception quality due to reduced intermodulation distortion and dropouts due to multi-path interference. (Directly replaces PA421A.)
The PA421B is compatible with Shure PSM300, PSM 900 and PSM 1000.
