Best way to repair/replace broken-off CR-V antenna?

it would be easiest to have it welded back together, but there's a wire that runs from your antennae down through the frame, behind the dashboard..you have to like cut it, and tie the new one on, and fish it through. then i think there's a connector at the end. it's been a while. very difficult if you don't fish it through.

The screw is actually threaded into both parts. If you cannot grab the remaining stub with a Vice grip or similar, get a set of Easy Outs (A tool specifically made for removing broken screws. They cost less than ten bucks.) and do it that way. Once the piece is out of the base the other half is an easy decision... If you can't get the half out of the antenna post, buy a new antenna post. They can be had for two dollars on a dozen websites. If you DO get both pieces out, any dealer will have the double ended screw stud in the parts department. They'll probably give it to you for free.

I had this problem, attacked it with a tiny drill in a Dremel, intending to create a slot for a screwdriver but the action of the drill just unscrewed it , job done.
