Duplexers

Duplexers
Duplexer/Splitter/Combiner
Comet calls these “duplexers”, 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 two radios at the same time into a dual-band antenna* Combine a dual-band radio with separate outputs into a dual-band antenna* Separate a single connector duplexed radio into separate antenna systems
* Allow a single coax run into two antennas at the top of the tower, and two radios at the bottom by using a duplexer at both ends of the coax run, avoiding cost and weight.
Choose from versions with a variety of band-pass frequency ranges, coax leads or no leads, and connector combinations.

CF-530C
HF-6M/2M-440MHz Duplexer for the FT-8900
This version has a coax lead and PL-259 connector on the COMMON port. This allows you to split the common connector on the FT-8900 back into two separate connectors: One for an HF-6M antenna, the other for 2M-440MHz antenna.
If desired, the 2M-440MHz connector on the CF-530C can then be split again if you want to use separate 2M and 440MHz antennas.

CF-706A

HF-6M/2M-440MHz duplexer for the IC-706/MKII/G, FT-100, etc..

To match the RX freq range of the IC-706MKII/G the CF-706A was engineered to pass the commercial FM band of 88-108MHz.
