Triplexers

Triplexer

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**  Using 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 connector….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!
