Four-to-one PSM antenna combiner

The Shure PA421B is an antenna combiner and is a useful accessory when using PSM in-ear monitoring systems. When multiple in-ear transmitters are installed in a case, the Shure PA421B allows 4 transmitters to operate from one antenna. This results in an improved RF signal and higher compatibility. The Shure antenna combiner operates in the RF frequency range of 470-865 MHz.

The PA421B is compatible with Shure PSM300, PSM900 and 1000 systems.
