Compact half-rack antenna combining system that distributes DC power and RF signal for up to four Shure PSM300 transmitters and significantly reduces the number of antennas and power supplies needed when using multiple systems. It features a wideband 470–865 MHz frequency range and provides main RF output connector that connects to any antenna with a BNC. The system also features RF LED indicators that display signal present and signal overload per input and a front panel power switch. The power output distributes DC power to PSM transmitters (accessory power cable required). Rack-mount and hardware kits, a 1/4 wave antenna, BNC bulkhead adapter and cable, power supply and power splitter cable are all included.
