Antenna Replacement FAQ
The radio antenna on my 1990 Jaguar XJ6 (XJ40) will not retract all the way into the fender, but shows about 5 inches when the radio is turned off. In addition, the head of the threaded shaft is broken off. So, I went to my local Jaguar Parts and Service place here in Tulsa, and bought a new antenna. Back at the garage, I managed to get the old one out, but there is about 5 inches of the white plastic lead that is missing. It could still be in the antenna motor and that's why the antenna doesn't retract all the way, or maybe it was broken off before it was installed and there is nothing in the antenna motor. Is there any way to tell, or do I just install the new antenna and hope for the best?

I assume you bought a mast with toothed plastic, and the plastic on the new one is longer than the one you removed from you antenna motor, What you will have to do is either power the unit with no antenna in it and you might get lucky and the broken part will come out (have the antenna tube facing down so the piece can fall out) or you can take the antenna motor apart and remove the broken piece( be careful when doing this take pictures as you go along ). I hope this helps you out

That's correct, Lumppy47.
I bought the mast with the toothed plastic line. I will attempt to do as you stated and turn it upside down and power the motor. It will have to wait until next week because my wife and I are celebrating our 34th today. And besides, I need to figure out how to remove the panel in the trunk so I can get to the antenna motor.
Thanks again.

Okay. I removed the side panel and accessed the antenna motor. Then I attempted to get any pieces that might be still in the motor out by turning it upside down and turning the radio on and off. Nothing came out, so I removed the antenna and took the cover off. There are no pieces of the old antenna in the motor, so I put it all back together and attempted to install the new antenna mast. I inserted the plastic toothed strip into the rod as told in the instructions, but it wouldn't go. The opening on the motor seems to be too small to accept the toothed strip and it takes a lot of force to get it in. Any ideas?

All is well. After sending that last reply, I went back out to the car and removed the antenna motor, took off the cover, and inserted the plastic toothed strip into the antenna mast tube. By visually observing the process, I was able to see where I was having difficulty and when I put everything back together and retried the installation of the mast, it all went together like a charm.
Thanks for the suggestions, Lumppy47. And I did take pictures and they did help!

As I said, the installation didn't go especially smoothly. I experienced difficulty in getting the gears on the motor to accept the plastic toothed strip from the new antenna mast. The attached pictures show some of the work involved.
The first step was to remove the spare tire and the jack. With the jack removed, it was a simple task to remove the rear panel. By the way, that is not the original rear panel. The original was water damaged, so I used it as a pattern and cut a new one out of luan plywood. With the rear panel removed, I removed the carpet on the floor of the trunk (boot?), then the plastic cover over the tail light. Next, I removed the side panel, using care not to bend or tear it. With the antenna motor exposed, I disconnected the antenna motor electrical connector, and the drain hose from the plastic drain at the bottom of the antenna motor. I removed the nut securing the ground strap at the top of the antenna motor tube, then unscrewed the antenna cable from the antenna motor tube. Finally, I removed the screw and washer securing the antenna motor mount bracket to the car body and removed the antenna motor. Once the antenna motor was removed, it was easy to remove the cover and look inside to see what the problem was. Assembly and installation was the reverse of the removal/disassembly.
Once I overcame my initial apprehension at doing the unknown, I really enjoyed it.
Apparently, I did something wrong. The pictures didn't attach and I'm not familiar with how to make them URL compliant, if that's even possible.

My antenna I found stays up. The motor assembly appears not to be mounted properly to the wing since the antenna "sloshes" a bit in the through hole and it's not the rubber grommet at fault. It's probably the reason my boot leaks when it rains.
I needed to pull the antenna so I could put a waterproof cover over my Cat for the winter.

I had to
- unscrew the mast with a wrench and tug on it a bit to make it bend at the joint w/o breaking the reception wire
- disconnect the motor mount assembly from inside the boot and
- pull everything into the boot, finally removing the entire electric aerial.
