get a screw that threads into the bottom of the antenna. then get a peice of rubber and put that between the screw, antenna, and chassis(drill hole into chassis). then you wil have to sand a small part of the antenna and solder the antenna wire to it. then make sure to cover any bare wires. i dont see why you would want to do this though, wont be much better, and if you flip the car, there goes the $10 antenna.
