The Shure PA411 Antenna Combiner distributes DC power and RF signal for up to four Shure PSM300 transmitters. The compact half-rack system significantly reduces the amount of antennas and power supplies needed when using multiple systems.

Features:
- Wideband 470 to 865 MHz frequency range
- Main RF output connects to standard 1/4" wave PSM antenna
- RF LED Indicators display signal present, signal overload per input
- Power output distributes DC power to PSM transmitters (accessory power cable required)
- Front panel power switch
