I bought the Cobra 29
I bought the Cobra 29 lx. It's a great looking with new features. When I connected my K30 antenna, all I got was antenna warning every time I keyed the mic. I saw a lot of videos about this problem. But I called Cobra for help. I have not used a CB in over 40 years. Do not have any of my old gear. They suggested trying a different antenna. So I bought the cobra mag mount. As soon as I connected it, all the antenna warnings went away. I was able to tune the antenna and get my SWR's down where they should be. The radio knew something was not right with the K30 antenna. I am glad I called and listened to Cobra.
