Are you asking if a manual antenna can be installed...or what?

Cheers

I don't see any reason why not. Neither the car nor the radio knows if the antena is power operated or not.

Doghead,

My antenna just went out today (must be something in the air)... can you post a pic of that relay? Mine is stuck in the up position and car cover will not go on now.

Thanks.....Scott

BTW... in addition the fuse keeps blowing on the antenna/interior light circuit. Did anyone else have this issue?

Assuming original parts and not aftermarket replacements, the antenna relay is usually lite green and mounted on or near the antenna motor....which is a couple feet away from the antenna itself, the two being connected by conduit with a cable inside. It's on the same fuse as (some of) the interior lights. When the fuse blows it can, on some models, cause the door lights to stay dimly lit at all times.

The relay incorporates a timer to delay retraction of the antenna

The fuel pump relay is on the firewall

The antenna or motor is probably jammed/seized...creating excessive draw and thus blowing the fuse. I'd pull the relay for the time being.

A pic would be helpful. Also... where did you find a new relay for the antenna? It has 5-6 wires on it, not like the fuel relay which is more generic.

The power antenna on my 76 XJ6 has been running great. But when I arrived home tonight and turned the car off the antenna did not retract. I checked the fuse in the truck near the spare and it had blown, I put in another and it blew. What could the issue be, could the relay be shot?

Default Power antenna failure

My antenna failed on my 77 XJ6 motor kept running it was a broken cable from the motor to the antenna itself. After a fruitless search for repair parts I decided to replace it with a manual. Found one on ebay for 20 bucks I believe it was for a toyota truck the angle for the chrome bezel is very steep so you have to be careful it fit perfectly with minor mods

My "new" 2007 Jag XK Antena doesn't retract all the way, leaves the last section up. Any ideas on why?
Thanks

Default Repair it

If you remove the entire apparatus from the car and clean it (especially the telescoping sections of the mast) There is a drain hole in the bottom of the motor casing to let water out. Water that has seeped in by coming down the mast settles in the bottom of the casing. These are easy to disassemble and clean, with the mast fully extended , wipe it with some light oil on a rag. If it has never been lubed dirt gets collected in the mast section and eventually the resistance to operate over comes the fuse rating and the fuse blows.

They are not that difficult to disassemble ,clean, reassemble. Mine on my 86 works just fine, but I make sure the telescoping action is clean, has been wiped with an oily rag recently and runs smoothly. Don't give up on it rather learn how it works - that's the beauty of these cars when every thing works they are quite a joy.
