Comet CF-706 Duplexer for Transceivers - HF-VHF/UHF

I have used Comet products for 20 years knowing I will get quality materials that consistently perform. I recommend Comet antennae and duplex/triplexers without reservation. KB7NES

It does what it is supposed to do but the female connector is weakly designed and mine failed after only a few uses. Its not replaceable so you need to throw it out when the connector fails. Ill try a different brand next time.

Works well, a must for the ATAS antenna!

I usually like Comet products but this Duplexer has very high SWR on 440MHz. Appears to be dead on UHF, VHF shows an SWR of 2:1. HF side seem to be okay. Took it out of service and replaced it with a antenna switch. I have another Comet duplexer that does work just different connector, also a Diamond duplexer for UHF and 1.2Ghz. Both work with no SWR issues.

As Described

I ordered this in error and returned it.

Flawless setup with my Yeasu FT-857 and ATAS-120a.
