Relay Antenna Box RAB 22

The RAB 22 unit is a relay operated antenna switch. The unit makes it possible to switch between two receiving active antennas, or between one active and one passive antenna. Irrespective of from which mode the antenna switch is in, the unit will always let the AM signal pass. It is possible to block the short wave receiving with an extra built in relay function. The RAB22 unit is designed for indoor mounting. If the unit for any reason must be mounted in an outdoor environment, special precautions must be taken. Recommended powersupply units are Pb3222 or PS3522.
