Shure PA821B Eight-channel Antenna Combiner, 470-865 MHz

The PA821B is an eight-to-one wideband active antenna combiner for Shure PSM wireless systems, operating from 470 to 865 MHz. It combines the RF outputs of up to eight P3T, P9T, or P10T transmitters into a single output feeding one transmit antenna, reducing intermodulation distortion and multipath dropouts. Eight input LEDs show signal presence and overload, and a quiet, temperature-sensitive fan limits noise and heat. Compatible with PSM 300, PSM 900, and PSM 1000.
