Solved it. I didn't see it before, but in the better light today I found some patent numbers. Looked them up, and they're antenna brackets. I'll have to look a little more closely to see if there are any diagrams or anything that show any holes being required, but the mystery is solved.

 

Further digging: no holes. Should be that crappy foam adhesive stuff with silicone adhesive around the perimeter. Cell phone antenna. Why two are needed has still not been explained.

 

I dontknow if you mean there are 2 of them on the car or that 2 of them were glued

Reception used to suck and some people thought it made you look more baller to have 2.
And if you mean they are hlued its because thats how it worked without drilling the hole. An actual antenna used to be screwed to the exterior.
I also remember seeing these on car service vehicles for the 2 way radios.


You should think of becoming a private investigator your investigative skills are too notch

 

They are glued because I read the patent referenced by the pat number I eventually found, and then followed through all the referenced patents as well.

 

..as he scratches his privates..under his "leaf"..(hahahaha)

 

I used to install those. Definitely old-school cell phone antennas, if there are two, it was a higher end system with diversity. Guarantee no drilling, use a twisting movement when removing it and you should be good.

 

What is "diversity"? I think I saw something about that related to the stereo package somewhere...

 

Yup. Here:

1986 (first image), ninth option down.

 

Nevermind. I thought it was some sort of brand thing, but it means having duplicate antennae with the intent that having multiple sources for the same signal can help eliminate interference. Interesting... I have the fanciest of 1986's fancy radio options in there with (however many) band EQ and all that good stuff. Works, I just don't listen to the radio when I drive!

 

For the AM/FM radio There was an antenna IN the glass as well as the metal whip antenna

 

What's the deal with the motorized up/down antenna on the fender then?

 

I believe the antenna in the back was for FM radio, and the one in the windshield was for AM

Old GM trucks had them in the windshield too

It was a 80s thing

 

they have both! diversity! compared to the earlier Rx7 with just the up/down antenna (in the US), the FC has better reception.

 

70s Mazda's had them in the windshield too..

 

Diversity antennae for the factory stereo - mine still has weak reception, especially AM; I suspect my factory stereo has a bad internal connection for one or possibly both antennae.

If it hadn't been confirmed already, I was going to say cell antenna for the original question, I had a 96 Passat that had a car phone in it with a similar antenna mount on the back glass.

 

in the USA we didn't get it until the FC. we never get the good stuff here, because we use lawyers to complain, a lot

 

Ok, skipped a bunch of posts. I'm afraid to admit I had one, back in '96 or '97. Took it off after a couple months.

It's a glass mount CB antenna. One part double-sided-tape on the inside, one on the outside. No holes drilled.

Don't ask. Maybe I thought I could listen in to the cops and truckers and it would be interesting. The novelty wore off fast.
