I'm sorry I don't remember the model of the Diamond antenna on my vehicle. It is a fold over, but it has a locking collar that has to turn 3 full turns to release. Basically impossible to be folded by road wind. I did have some trouble with the cheap coax end on the coax that came with it, it was slightly undersized and if I hit a tree branch the whole antenna fell off the truck. Until I replaced it with a proper end, I kept a safety string attached to the antenna so when it decoupled, it was still where I could find it.
