Which original antenna for 911 from 69-73?

[Cliff]

This is what remains of a 72 T. Presumably original to the car.

'72 T here, as well.

Both look good to me. Auta 4900 LS 18 is the same up top.

'72 T here, as well.

Still has the black plastic cover over the tip of the antenna. Pop that off (I don't recommend that, though) and you will expose the metal end of the antenna with the slot for the "key". You will now be able to push the antenna tip into the receiver and will require the key to lift it up. The plastic cover is there to keep it from retracting all the way. I don't recall this ever being mentioned. Just more useless info.

Regards

Jim
PS: The 3rd picture in post #3 shows the tip with the cover removed.

65-73 the factory option for manual antenna was Hirschmann AUTA 4000 C71L.

The antenna modell changed sometimes during 1973. The correct antenna then was Hirschmann Auta 4000 M 801 (Teleskop schwarz verchromt, flacher Einbau) and the antenna was 110 cm, 4 section mast, fixed mounting antenna base 15 degrees, cable length 150 cm with plug Kast 50.
That year Hirschmann changed the power antenna model designated for Porsche.

I have more than one original 73 car with the previously referenced chrome antenna. I have never seen what I believe to be an original 73 with a black antenna. I currently have two 74 cars optioned with black trim that have a black antenna. In my opinion, the switch was made sometime in 73 but only for 74 cars so optioned.

I'm not sure exakt when they changed to black chromating.

I just took the information from the Hirschmann car antennas and installation suggestions 1973/74.

I read an article in Excellence magazine, about the 731-mile 1973 911T "The Raymond Allen 911T" and I think that car had a black chromed antenna. I have been looking at pictures of this car posted on the forum, and it looks like a black chromed antenna, but it is a little difficult to determine (see pics in post 5, 7, 23 and 41)

I'm trying to buy a 11k-mile, one owner 73S right now. It's a late-build car and the original antenna is the standard chrome.

I have searched and collected some information regarding the power antennas that Porsche used and thought to share what I found. The Hirschman Auta 6000 serie D type 35 was Porsche´s automatic antenna option used on the 356 and also on the 911 SWB. You can see pictures off that specific antenna in this link (see http://derwhites356literature.com/35...oriesLATE.html and in Workshop Manual, vol 11, section TRA). The Hirschmann Auta 6000 Serie D was superseeded by the Auta F serie. My source at Hirschmann have told me that the Hirschman Auta 6000 serie F type 851 (ord code 923 733-000) was Porsche´s automatic antenna option from late sixties (propably end 68/ early 69, since the Hirschmann installation manual for that specifik antenna is dated 13 th december 1968 and for 912, 911 T, E, S). The F series was manufactured until year 1973. But the later H series was manufactured/sold from 1971. I cant tell the exact year/date when Porsche changed to serie H (type 852/853, specifik for Porsche).
I´ve checked ”The Hirschmann car antennas and installation suggestions 1973/74” and it says Auto 6000 H, but the catalouge has no print date. I dont have the earlier catalogs. I noticed some one have posted the catalouge online https://vdhflipbooks.de/books/KAT/KA...e/index.html#1 My contact on Hirschmann havent been able to give me the exact date. The Auta 6000 H model replaced the F model. Porsche then used the Hirschman Auta 6000 series H, type 852 S (924 992-001) and type 853 S (920 059-001). visible external changes were that the position on the antenna hole on the right front fender was changed and that the base was black chrome. They were big and heavy (the type 852 S weights 2905 g). I haven't weighed the D or F series, but they´re are also heavy. Its hard to find reference pictures of survivors (on the model D, F and H). I’ve only seen photos on these early power antennas installed on Porsches in the specifiks antenna installation manuals. I think a Porsche factory installed electric antenna were a very rare option. The electric antennas were large and they were exposed in the wheelhouse, so probably the life time was pretty short.
I have antennas of the D, F, H model, so if anyone wants to see pictures, just let me know.
Please feel free to correct the above information, if you think I´ve got it wrong.
