Comet CF-530C HF/6M/2M-70cm Duplexer

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 connector for an HF-6M antenna, the other connector for a 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.
