Comet CF-530 Duplexer 1.3-90/125-470MHz, 600W, SO-239

Wideband Dual-Band Duplexer for HF, VHF and UHF

The Comet CF-530 is a high-quality wideband duplexer designed for simultaneous transmission and reception across two broad frequency ranges — 1.3–90MHz (covering HF and 6m) and 125–470MHz (covering 2m and 70cm). With more than 45dB of isolation between ports and a flat 600W PEP power rating across all bands, it is one of the most versatile duplexers in the Comet range. Combined bandpass filters suppress TVI effectively. The unused port can remain open, though terminating with a dummy load is recommended.
