My comet setup - clinging to the edge of the hood - works fine for my little scanner antenna. I like the rigidity of your setup for a serious CB antenna. I'll be curious to see how it holds up against brush and tree branches though!

I use a QD mount on my CB, so I can more easily pop it off, since most of my travels are around town and I don't use the CB then. Going to Buffalo this weekend though, so I'll be fully deployed. Thing is, most Pittsburgh parking garages discriminate against CB-Americans - my barrel mount still smacks cross-beams in most of them.
