Hirschmann Antenna pin-out question - PeachParts Mercedes-Benz Forum

waybomb · #1 04-04-2004, 06:32 PM

Hello
I have a 1982 300SD. The car came with an el-cheapo $29.00 Hirschmann replacement antenna that doesn't even fit the hole in the body correctly, leaks water into the trunk, and does not function. I found two OEM Hirschmann antennas, part number 126 820 03 75. One is serial number 38 3 04, and the other's serial number is 02 4 05.
As stated above, the previous owner replaced the OEM with a cheap replacement. The original wiring connector on the car was left intact. However, the two replacements I bought were made for a different size connector, and oriented differently than that on my car.
Anyway, does anybody know which car wire goes to which antenna prong from the 1982 126 car to either of these two antennas?
Thanks
Fred

Does anybody know - does pin 1 on an older antenna = pin 1 on a newer antenna? Five pins total each on the plug and the antenna, but the antenna is configured with the pins closer together.
Anyone?
How about schematics?

Thanks
Fred

Hello
Got home this weekend for Easter and opened my CD repair manual.
The car originally came with a Hirschmann 6000, and what I've found in the manual is that Hirschmann stopped making the 6000 model and replaced it with a Hirschmann 6000EL. At that time, an adapter harness was to be purchased and the antenna switch was to have a jumper installed.
I am not an electrical genius and the schematics don't help me out, but could one of you look at the schematics and tell me which wires hook to which post so I could simply raise and lower the mast with the switch? I can live without the automatic function.
Or better yet - where can I buy the necessary adapter kit?
Or, does somebody want to trade my two 6000EL antennas for one operational 6000? One of the ELs has a busted mast, the other seems ok.
Thanks

So what you want to do is replace the 'el cheapo' in the 82 300SD with the working 6000EL that you have? And the plug on the 6000EL antenna doesn't match the one on the car wiring harness? If this is all correct, what are you running the antenna from, an original Becker radio/cassette or aftermarket? And does your car have a dash mounted 'antenna switch', designed to bump it up/down in increments?
Sorry for all the Q's, but we can probably help better/easier with the complete picture.

Meantime, here's a great shop that might be helpful. If you look under make/year, they sell several adapters that look like what you want.

However, if it were me, I'd rather save the money and hassle and just wire your working 6000EL into the harness to go up and down with the radio on/off and skip the complexities of the dash antenna switch (if you have one, that is).

The one with the broken mast might be easily and more cheaply fixed by just replacing the mast. Unless your saying the one the PO bought which didn't fit was the only option.

donbryce said "I'd rather save the money and hassle and just wire your working 6000EL into the harness to go up and down with the radio on/off and skip the complexities of the dash antenna switch (if you have one, that is)." That's eactly what I want to do. Which wire from my harness for the 6000 goes to which wire on the 6000EL?

delsman - the PO put in a piece of junk that does not fit right or seal against the body. The 6000EL seals just like the original 6000, but I'd like it to go up and down.

I currently have the 6000EL with the broken mast installed with the antenna pulled all the way out, but i'd like the radio to make it go up and down.

Thanks

The only "good" way to fix this up is to get the adapter. It should have came with the EL mast, so look around to see if the PO left it in the car. Otherwise it should be able to be ordered seperately I believe. Maybe Phil at PartsShop can find it for you, or a dealer should. It will come with the instructions on what goes where, that should be the easiest way, otherwise I can try digging for info. Once this is adapted, the middle position of the switch won't work as original, I'm not sure exactly what the middle posion of the switch does after installing the EL, it should be either OFF or MAX, not sure which.

Phil - can you supply the adapter Gilly refers to?
Thanks

What was the outcome on this issue? I am having a similar problem trying to replace the power antenna on an 84 300D. The antenna which Fastlane sells for this application is completely different than the original, so the wiring is incompatible. If an adapter harness is available it might resolve the problem, but I can't really make heads or tails of the Antennaworld information.

FWIW, whenever I've had to replace an antanna assembly on an older Benz like this, the harness and connectors I needed came with the antenna assembly, along with instructions. I believe there is an old DTB about this modification also, but everything was in the box.

Thanks Gilly. Well, the one from Fastlane is, if I remember right, a 201 part. It did not come with any adaptor harness. Then I went through the same exercise with another vendor. Same deal, they insist it's the right part, but it obviously isn't. I guess I will try the local dealer and see what they have to say. How would one go about getting a copy of the DSB? I have all the TSB's for this car, but nothing related to the antenna in there.

Palangi · #12 05-06-2004, 05:58 PM

Well, my mistake, as usual. I looked at the antenna I bought from Fastlane more closely. It does indeed contain a package of parts and a diagram showing how to adapt it to 107 and 123 chassis. The little bag of parts was hidden under some packing material, I just hadn't looked closely enough before. So, once again, Fastlane rules and Performance Products drools!

Part number for the antenna is 201 820 01 75 .

Part number on the kit of parts is 201 820 01 75 80 , but not sure if it's available separately, and not sure if this applies to 126 cars or not.
