Looks like he doesn't from the pics.
I have the same setup as stan...with a spring. Located in pretty much the same spot. I don't jump mine like stan does, but even with wheeling and such mine has never hit the top. My spring is relatively stiff, but does help out a lot
I no longer have the 4' FireStik on the back, I now use a Wilson "Lil Wil" magnet roof antenna. Performs much better since its above the truck entirely and it's a much cleaner install as far as coax goes.
