    Radio antenna goes up only 15 inches. 1990 XJS V12 convertible

    Greeting,
    the car still has its original radio. The antenna goes up when the radio is turned on. It just doesn’t go up high enough to get good reception. Any ideas for me to check out? Your help is appreciated. Thank you!

    When the aerial starts to go up, get hold of the top and help it on its way. You will find the mast is probably stuck. When you have it all the way up, thoroughly clean and lubricate the mast then try again.

    I do not offer advice, I only say what I would do with the set of circumstances presented. Your choice always.

    Well, I did lubricate the antenna mast with Liquid Wrench and pulled up on the antenna as it extended. One section did free up. Another section does not seem to want to free up. I don’t want to damage the antenna, so I’ll try this for a while. Thanks again for the tip.

    Undo the top nut, turn on the aerial and the sections and nylon winder will come out. Easy then to clean/lubricate as necessary.
