This is a dual band antenna from Comet. Its a ground independent type. That's why I can use the roof rack type mount. It isn't manufacture anymore. That's a shame since it has a very wide band response. I tested it on both the Ham 2M and 70cm bands, good match over the range. The antenna will also work for MURS and GMRS.
I sold my Jeep, photo, and replaced it with a 2023 Mazda CX-5 2.5L Turbo Signature model. I had the optional roof rack and rails installed on it. Now I have to mount the antenna system on it at some point and find a good way to route the cable inside. I'll likely buy new rack mount hardware and cable assembly since the old one is weathered fairly well.
