DISTRO4™ is a broadband UHF (470-952 MHz) antenna distribution amplifier that routes antenna signals from a pair of diversity antennas to several receivers in a multichannel system. Four amplified outputs compensate for signal strength lost in the splitting process. Two or more units may be cascaded together to accommodate setups with larger channel counts.

DISTRO4™ features a 2000 mA internal power supply (no wall wart) and compares to antenna distributors twice its price. For active antennas and in-line amplifiers, DISTRO4™ provides an internal switch to apply 12V DC power over coaxial cable to antenna connections. It includes all RF and DC power cables needed to connect a 4-channel wireless microphone system, as well as cascade to one additional DISTRO4™.
