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

Works as designed, good Duplexer.

Work great

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

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.

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.

works as intended

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

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

Needed a way to be able to split one antenna into the two connectors and this works great.

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.
