1972 350sl front antenna

[Ameliajackson]

Hi
The automatic antenna on my 1972 350sl (R107) has been misbehaving. It continues to try to wind down the aerial after it is fully down - resulting in a flat battery. I've disconnected it from the Becker head unit for now but does anyone know how to get at the antenna? It's situated on the off side front wing (car is a right hand drive). There seems to be no way in from under the bonnet or from inside the car. I know that most of these cars had the antenna in the boot - which is probably a better idea but not much help to me.

I'm sure there's a simple answer to this!

Thanks

You might need to go up inside the wheel arch from outside the car, if you put the steering on full lock you might get a better view.
