Open Box Shure PA821BX Eight-channel Antenna Combiner, 865-960 MHz Level 2 197881135591

The Shure 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 eight 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 multipath interference.
