📡 Comet SS-680SBNMO 2M/70cm Mobile Spring Antenna (Black) - High Performance, 2.15/4.15 Gain, 27" Length, NMO Connector Review

I am satisfied with the performance. I have not found any other antenna of this size on the market that performs as well as this one.

I bought this antenna to fit my camper and it still works well. I had another that didn't have a spring section and wanted something that would flex when hitting a branch.

This antenna worked very well. Easily mounts to the NMO mount and handles speeds of up to 80mph with no issues. Contacts are clear and my transmissions seem clear too.

Although smaller than the competitor antenna I've had on the F250 bed rails, this antenna definitely outperforms them. I expected worse and was pleasantly surprised, especially in the 70cm range. 2020 update: It outperforms the CX-333, which is taller and stands at 18ft at home.

Performance on 2m is just basic, so the performance of the UHF side of the antenna is acceptable. The antenna is roof mounted on the 2016 Prius and still allows me to pull into the underground parking garage in about 6ft 10in. I would recommend this antenna to anyone who needs dual band performance in a small rooftop antenna.

I installed this on the hood of my Honda Pilot using a lip mount. It goes well with my black car and my wife is comfortable driving it. With my analyzer I get about 1.1:1 SWR on most of the 2m band and just under 2:1 on the 70cm band, which is acceptable to me, although I can try to trim the 70cm band a bit improve by fiddling with mount. I get good performance out of it. I can subjectively hit any repeater I want to hit, even distant ones. love this antenna.

I bought this to fit my motorhome and it still works fine. I had another that didn't have a spring section and wanted something that would flex when hitting a branch.

I installed this on the roof of my SUV with a Larsen NMO2/70B. This antenna is with my Yaesu FT3D for APRS connected and my Larsen is connected to my Icom 2730. The Larsen is said to be an excellent antenna but my Yaesu is picking up something that Icom can't, I'm not entirely sure if this is more to do with the antenna or the sensitivity of the receivers on the radio has to do, but I think it certainly speaks to the performance of this antenna compared to the larger and 'decent' proprietary…
