New to forum, and CB’s . I dabbled some years ago with a mobile, but never a base. Here is my greenhorn question: i have a 30x40 metal shop building i want to mount my A99 to roof peak, prefferably using a metal pipe, from ground to as far past peak as i can, then attach A99 to it. My plan is the roof peak for stability as high as possible. Now, should some type ground be hooked up ? What keeps lightning from travelling coax to my radio ? Its a used cobra 29ltd. I have a power supply. Is there some type lightning arrestor! Does calmping antenna to pole take care of this ? I hear about ground planes, would metal roof serve as that ? Thanks in advance for any advice
