You can also buy a foldover to screw into the mount .
If you want to put the top on and off , your going to have to do a bumper or bedside mount , both vunerable to damage .
Can't have good performance , and protection , if you really wheel .
A flexy wire whip , through a hole in the top , will probably flex well with branches . Since the roll bar and top will be seperated a little , and the whip will flex against the top , not putting pressure on the mount .
Just need to install top , and then put whip through hole ( with a little holr plug gasket type thingy ) .
