I am assuming you bought the generic Hirschman antennae... I think it is
2040... I did this to my car... the grounding is though the chassis mount.
You can see the black wire is supposed to be mounted to the mouting
bracket... which is then attached to the body chassis... hence the ground.

Tiger's right. I bought a Hirschman to replace the old, broken MB that came
with my wife's '81 300D. I simply installed the antenna, hooked up the black
ground wire to the inner fender well "fin", plugged the blue wire from the
antenna up/down sensor into the corresponding wire in the MB plug, found the
"always hot" wire, and plugged the antenna "always hot" lead into that. The
wiring instructions with the antenna were pretty much straight forward.
Viola, everything has worked perfect since.
