The RF MULTI Mini SMA contains two separate active 1x3 RF splitters for use with up to three diversity receivers. This is compatible with frequencies from 470 to 700Mhz. Two BNC connectors connect the RF MULTI Mini SMA to external antennas, which can also be powered directly from the split. A switch on the top controls power to the splitter and power to the antenna. The RF MULTI Mini SMA can handle voltages between 10 and 15Vdc via a 4-pin Hirose.
