Features 1、The MX62N duplexer is a series of inductance coils and capacitors that acts as a band‑pass filter. 2、Combines the output of the HF/VHF transceiver and the output of the UHF transceiver so that both transceivers can be connected to the same antenna. 3、Can also be used to separate UHF/VHF transmissions from UHF transmissions so that one transceiver can be connected to two antennas. 4、The MX62N duplexer can be used in two different ways, used in different frequency, can not transmit at the same time. 5、The MX62 VHF + UHF duplexer is designed for indoor use, usage frequency is 1.6‑55MHz / 144‑148MHz&400‑470MHz.
