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

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

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.

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

I ordered this in error and returned it.

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.

does a good job

Great duplexes. I got it as part of a combo package and it works, perfectly, as most Comet products.

Work great

Works...
