6.6.4 - Electric Antenna Mast ( all models ) ( Gregory Wells, Coventry West,  )

It is possible to replace the antenna mast on 1988 and later Jaguar sedans, so long as the mast is the only problem (it is not unknown for the motors to go bad). And the replacement can usually be accomplished from outside the car with nothing more than a wrench.

The antenna mast is held into the antenna motor assembly by a ferrule nut at the base of the mast on top of the rear fender. Undo this nut and then have someone turn the radio on. As the antenna or cord is pushed up, simply continue to pull and it will come out. While the mast or cord is being ejected, note which direction the cord's teeth point.

Compare the length of the cord from the old mast to the length of the cord on the new mast. They should be very close in length. If the old mast is much shorter, there is the possibility that a length of cord has broken off and is still in the antenna assembly. If this is the case, the assembly has to be dismantled to remove the piece of cord, as the reel only has enough space for one antenna's length of cord.

With the radio still on and the antenna motor still in the extended position, insert the tip on the new mast's cord as far as possible into the hole, making certain to point the teeth in the same direction as the old mast's cord. Have someone turn the radio off and if you have the new mast's cord inserted far enough into the antenna, it will begin to be reeled in. Don't worry if the antenna doesn't go all the way down in one cycle. Just tighten the ferrule nut to retain the new mast and cycle the radio on and off a couple of more times and the antenna should seat properly when off.
