I don't have a CB in my truck. I use that for the scanner. Never had a problom with the NMO mounts, I think CB is kind of dead, at least in my area.That is a good looking setup. Do you notice any reception issues with that antenna setup? I have my ham radio nmo mounted to the roof of my truck and then a cb mag mount about a foot behind it (like yours appears to be in the middle there) and it seems like my cb doesn't pick up signals like it used to.
