I own a 1976 Series II Jaguar V12 Coupe. It has a Phillips am/fm radio with a tape player, all of which work fine. My concern is that the rear-wing mounted radio antenna will not extend and retract with any regularity. The motor works fine. Information provided on the motor casing is as follows: "Radiomobile Product, made in Japan, Radiomobile Limited, Goodwood Works, N. Circular Road, London, NW2, 7JS, 52-622."

I believe the problem may be with the ribbed antenna motor reel that is held in place on its threaded shaft by a 10mm nut. I also believe that the width of that antenna reel is determined by the tightness of the nut on that shaft. When the antenna reel is properly adjusted, the antenna line should move out and in, allowing the sectioned antenna to move up and down. Unfortunately, I don’t know how to adjust the nut in question, whether it needs further tightening and, if so, how much.

I recently replaced the antenna line and had removed the nut from the antenna reel shaft. After repositioning the nut, I thought that by clamping the new antenna line onto the antenna motor reel and turning the radio off, the line would automatically rewind itself onto the spool inside the motor. It did not. At present, the antenna line does not move at all even though the motor cycles properly, both clockwise and anti-clockwise and the antenna motor reel turns.

I don’t want to do any damage to the reel itself nor do I want to strip the threads on the shaft the nut screws onto. Is there a manual available for this unit and, if so, is it one that I can download? If there is no manual, could you provide instructions as to how I might achieve the desired antenna extension and retraction.

Thank you for your assistance in this matter.

hi dave only done one several years ago and wound plastic line manually to ensure spool located properly as very easy to damage teeth on the plastic line. In the ninetys we used to supply a maystar electric aerial that was small enough to fit in the wing but had the right base fittings for the xj. we sold a lot to our local jag parts specialists. they may still exist. i know it,s cheating but they looked close enough to the original and came with chrome, stainless or black mast. i think the part number was b4000 but don.t hold me to that as memory isn,t what it was.
good luck

Thanks for the post, Simon. Sorry for the delay in responding. We've been away. The Maystar aerial may be the solution. Your memory is good as the part # was spot on.
