Triplexers
Triplexer/Splitter/Combiner
Comet calls these “triplexers”, but they are also referred to as combiners or splitters.
They are basically band-pass filters, simultaneously passing RF in both directions through the common connector while the band-pass filters provide a high degree of isolation between ports.
TX and RX from three separate radios, at the same time, into a single triband antenna
Combine a triband radio with three separate antenna outputs into a single triband antenna
Allow a single coax run into three antennas at the top of the tower, and three radios at the bottom, by using a triplexer at both ends of the coax run, avoiding cost and weight
Choose from versions with a variety of band-pass frequency ranges, with or without coax leads, and connector combinations.
**NOTE** How to use a dualband radio, and a separate 220MHz radio, into a single triband antenna
We are frequently asked if we have a Duplexer or Triplexer that will allow a dualband radio (with a single connector), and a single band 220MHz radio, to be used with the Comet CX-333 triband base antenna and/or Comet SBB-224 triband mobile antenna.
The answer is: You need to use both a duplexer AND a triplexer to accomplish that.
First: Use the CF-4160J, with the common port screwed into the dualband radio, you’ll need your own jumper terminating in a PL-259 on both ends. With the CF-4160J in place you have effectively turned the single connector on the radio back into two separate antenna connectors….one for 2M and one for 440.
Next: Use the Comet CFX-324A triplexer
The 2M connector on the CFX-324A screws into the 2M port on the CF-4160J
The 220Mz connector on the CFX-324A screws into the 220MHz radio
The 440MHz connector on the CFX-324A screws into the 440MHz port on the CF-4160J
This enables TX and RX on all three bands simultaneously!

2M/220/440MHz Triplexer
The connectors on the CFX-324J are all female UHF connectors (SO-239s)
Primarily used in a base station set-up to be easily located anywhere in your shack that is most convenient by adding your own jumpers between the radio(s) and the CFX-324J.

There are several other HF-6M/2M/440MHz triplexers with different coax connector combinations
CFX-514N: Same as CFX-514, but has an N-Conn on 440MHz
CFX-5140: Same as CFX-514, but without coax leads
