Can I JB weld radio antenna to the base?
 
To make a long a story short, I have stripped the nipple on the antenna base attached to the body. Bought a universal whip and it would fit if the threads were OK. So my question is would JB weld work? Is it electrically conductive or may be there is still enough metal to metal contact to work? If I knew for sure the nipple would screw out I would force it but it doesn't budge.

Maybe....but Id get a new set up

back in my rc car days with stripped bolt holes in alumnuim engine blocks we use to put pieces if steel wool from a brillo pad in the thread holes,screw in the bolts and the threads would hold for awhile


could you possibly drill a hole and put a cotter pin holding the antenna on?

try the jb weld,most people swear by the stuff.I think its a gimmick and only serves well on certain things.....not everything

loctite makes some stronger metal like two part epoxies

I would just replace the antenna base. It is outrageously easy to do. The 'cap' pops off, revealing three screws. Remove those screws and the base lifts away from the body. Now grab a good base off a junkyard TJ and put it on your Jeep, then screw your antenna onto the base. Problem solved.

Sherpa, I tried to pop it off but as you can see the screw is in the way. How do you get around that without cutting it?

No and no. As others said, install a new antenna mount.

I did this swap on my fourth TJ. In that vehicle's case, the antenna was missing and the base was kinda crunched, but it didn't impede removal of the cap. In your case, you're gonna need to remove that screw. It should be very quick work for a grinding wheel; if you don't have one, you could probably do the job with a hacksaw... but be very careful not to hurt your Jeep's finish!

When I bought a new antenna base from a junkyard Jeep, I also bought its matching antenna since I didn't have one.

You can use JB weld but you will sacrifice signal strength. JB weld is conducted but not at the same rate as the rest of the metal. On a CB you want as a little interference as possible.

Have you ever used an ohmmeter to see how conductive JB-Weld, an epoxy, is? Try it and you'll see it's not a conductor. JB-Weld has iron filings in it but because it is an epoxy, JB-Weld is not conductive. You don't want to use JB-Weld between pieces that have to be electrically connected with each other.

JB-Weld confirms their product is actually an insulator at http://jbweld.net/faq.php where they say:

"Q: Will J-B Weld conduct electricity?
A: No. J-B Weld is not considered to be a conductor. It is an insulator. "

I can cut the screw with my Dremel tool but I have to first make sure I can get the base. Looking for it in a junk yard is not a real option. This is what I have done in the meantime. Wrapped a few layers of teflon tape and screwed the antenna over it. It is holding for now and the radio works.

Barely... teflon tape is an insulator and should not be placed between an antenna and its mount.

I think there are a couple people parting out TJs in the for sale section.

Since you still have some stud sticking up, you could try this route.

It is supposted to attach with set screws coming in from the side of the base.

Ah, set screw. It is brilliant, Sparky! Thank you.
