I am about to remove the original Becker radio
from my '79 w116 300sd. I really like the feature
that controls to antenna, allowing a partial or a full
extention (or none at all) when the radio is turned on
through the use of the switch on the dash. I need to
know if I can route the antenna lead from the replacement
stereo head unit, though the switch and have it work like
original. If anyone knows the actual color of the wire so I
don't have to dig too far up into the dash that would be
Thanks for any information!
It is a question of the type of power antenna you have. Today they sell
fully automatic antennas, which are controlled by a single 12 volt line. If
you switch on the current, the antenna comes out entirely. If you switch
off the current, the antenna collapses entirely. Most contemporary car
stereos have a contact for this. As soon as you switch on the unit, the
contact gets 12 volt current and the antenna goes up. Some decades ago you
could also buy semi-automatic power antennas, which had a switch for
manually move them up or down. I have an automatic antenna in my car, but I
have installed an additional switch in the control line between antenna and
car stereo. So I can retract the antenna even if the radio is switched on,
for example when I want to listen to CD or if the car is in the car wash.
The antenna will retract anyway as soon as I switch off the radio.
I do not see any purpose in having the antenna stopped halfways. It is my
understanding that the length of the antenna is adjusted for best reading

I have the original factory antenna, unbeleivable
as it sounds. My car was taken care of by a single
owner who serviced it at the dealer, so when I got it
from his son (upon his inability to drive anymore) it was
pretty much completely stock, radio antenna no upgrades
The factory antenna and radio are hooked to a switch on the
dash, the switch has three settings, one allows full travel of
the antenna (when radio is switched on) one position allows
travel half way up, the other position keeps the antenna down
when the radio is on. (pehaps for playing tapes)
I like this feature, for whatever reason, and want to keep it
when I take out my (now defunct) factory Becker radio.
The best place I know for information and all the connectors and
you will need is:
they are very good with instructional information for any make of
they fixed me with my 1990 300SEL and my 1994 Pathfinder.. verything
Remove radio. Check to see if there is any info "a decal" about the
electrical conections on the radio. If so check the plug and you can
see which wire it is. You will need a wiring diagram for your car to
figure how to make the anteni work the way you want. You could set up a
switch separate from the new radio so you can manually switch the
antenni position. See Chilton manuels.
