what's wrong with a wilson 5000? easy to mount and remove, flexible, a lot less than some of the other mentioned ants. and will handle 1K watts
On my roll bar i have a metel plate where the KC lights are... Im sure i can have a buddy build me a plate for it... If mounting it perm is better than thats what ill go with... I would go out and take a pic of what im working with but its -3
