Hello folks, I'm new to CB radios, so I apologize for my naivety, but I have an older ram that has this mount located on the roof. I've found that a 3/4 nmo cap fits it, but the nmo adapter that I inherited gets hung up on the center pin. I've found a pl-239 connector inside the truck that appears to run up to the roof, as well as another connector that is basically a smaller version of the pl-239. I'm wondering what type of antenna I need to go on this mount, as I'd like to use it, as well as which connector it might go to, if you have any idea, please let me know. Thanks.
