Have you ever thought about punching a hole in the roof of your Trans Am so you could have the same CB antenna as the Bandit? The antenna used on the movie car is model M-176 by Antenna Specialists. It requires that you drill a 3/8" hole in your roof for mounting.
If you don't want to drill a hole in your roof, but still want to be movie correct, here is an alternate idea...
After the Trans Am bust through the dugout it has a black and chrome magnetic mount antenna on the roof. I know it is magnetic because 2 seconds later a board easily knocks it off the roof.
So now you can go with a magnetic mount antenna or no antenna at all and still be technically movie accurate. You are welcome!
If anyone knows the model of the magnetic antenna, please chime in. I haven't figured it out yet.
