KDUP-4091
VHF Duplexer
This VHF Duplexer allows a VHF transceiver to work in full duplex mode or simplex mode on one antenna. The duplex mode is controlled by the VHF transceiver, so that the duplexer can be selected or bypassed by coaxial relays.
Fully integrated inside a 19″ – 2U rack with optional power supply from 100/240 VAC – 50/60Hz (with +12VDC possibility) for easy installation. Basic LEDs on the front panel show local status indications.
