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

Works...

Excellent unit. Light and compact perfect with yeasu atas 120a and ft857

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.

The response to my order be placed was promp and I would order from the again.

As Described

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

Seems like it has loss below specs, and does what its supposed to. For me, thats to connect an antenna primarily designed for VHF-UHF to be attached to both the VHF/UHF and HF connectors on an all-band amateur transceiver.

I bought this for a mobile install for my Yaesu 857D radio and it works like a champ. It’s connected to an ATAS-120A antenna, so this is perfect. The device is larger than I expected, but I didn’t have any trouble tucking it away under the dash.

Works as designed, good Duplexer.

High quality and well made we are using this Im a solar powered repeater it connects two handhelds and shares an 8 ft antenna , def a good purchase for price and will last
