I also run the Bandi mount.
Mine was #6 when Bandi was cranking them out before he sold the rights to AllProOffroad.
It is really a good way to go on an FJ Cruiser as it looks like it came from the factory.
I use to run the ARB mount up front on the ARB bumper on my old rig, the '91 4Runner.
I prefer the antenna back aft, less of a distraction that way.
