Multicoupler ND-VHF-50 Duplexer

Multicoupler ND-VHF-50 is a 50W band reject "notch" duplexer designed to allow a two way radio repeater (signal booster) to transmit and receive on the a single antenna with excellent TX/RX isolation.

This notch duplexer rejects the frequency unwanted on the port used - the port used for receive (RX) rejects the transmit (TX) signal and port used for transmit rejects the receive signal. This ensures there is no crosstalk between TX and RX and allows a repeater to use a single antenna.
