I have the cobra 75, which works great for me and the antenna is wired up with the cool tech license plate mount.
That's what I have.
I went with that because the CB part that you use quickly detaches from a small base (where the antenna and power connect). The base stays mounted in my JK, hidden under the glove box area. Since the CB part is easily/quickly detached/reattached, I only have it in my JK on trail runs when I need it. The rest of the time it's in my garage.
I run w/o doors from May-Oct, so I like not having to worry about a permanently mounted CB that can be stolen or gotten wet.
I got the entire kit (CB, antenna, coax, receiver mount) from CoolTech. It's been great. I did change from the license plate mount to the gate mount after 3 years because I kept hitting my license plate when off-road, so I moved it (and the antenna) to the tailgate.
