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

Works as designed, good Duplexer.

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

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

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

Everything as stated on product listing. Arrived on time. Works as advertised. Very good quality, would not hesitate to purchase again.

works as intended

As Described

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 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...
