 Sure you can drive around with a tall antenna!!! My dad's TV repair Chevy
 van had a 102" stainless steel whip mounted right in the middle of the roof
 back in the '60's ...best mobile CB radio antenna configuration you could have.
 It beat the hell out of all the tree branches he went under though. I used to
 have a co-phased pair of 96" fiberglass whips on the back bumper of my old
 '78 Ford LTD back in the CB craze days. They made for a darned good FM radio
 antenna as long as the car was pointed somewhat in the direction of the
 station since this setup was pretty directional. Out on the highway at speed,
 they would lay down almost parallel with the road :-)
