CB antenna on Sissybar????

Hey I have bought a J&M License plate mount antenna and well Iam in the process of removing the tag from the fender on my C and putting a Side mount plate. I am wanting to maybe modify this thing to mount on Sissy bar. 1st question is there any out there already like this that will mount to sissybar and/or anybody ever modify one or made a bracket and could show pics.
Also trying to make it so it could be taken off with my Paladin (SUCKS) backrest so any ideas on cable quick disconnects.
Thanks

This may be a mute point, but I just ordered all my CB stuff from Sierra Electronics, and they have a sissybar mount for their JMCB-2003 units: http://sierra-mc.com/products.asp?cat=245
