Model CF-416A is the duplexer for transmitting/receiving all 2 bands of 144 MHz (included HF to 50 MHz) and 430, 440 MHz at the same time.
Using one, or two CF-416A, you can connect transceivers and antennas by one coaxial cable.
The combined high quality filters of CF-416A work to prevent of occurrence of TVI on the other hand (isolation of each connectors are over 60 dB)
When using CF-416A for one frequency, the other connectors can be remain as (open), but additional dummy load will be much better.
Frequency range: 1.3-170 / 350-540 MHz
