How do i repair the antenna,it got snapped off?

Perhaps you can use a broken screw remover that you can purchase from you local hardware store.

rod screw type antenna you have to replace whole antenna.just screw out old antenna screw new antenna in place.

Remove the antenna and buy a repair kit from the dealer.

@womonsoft7 I'm giddy with childish excitement because this actually worked for me "If you're lucky, you can sometimes just push a screwdriver against the edge of the screw and rotate the screw out that way". After reading this I thought it would be worth a try...It just happened to be loose enough for this to work. My Antenna was broken off by a low clearance garage door, actually thought I smashed in the roof, but it was just the antenna. Easiest fix imaginable.

If the remainder of the bolt protrudes above the surrounding metal(you'll need about 1mm), you can cut a groove with a hacksaw into the bolt and screw it out with a screwdriver. If this is not possible you can use an "Easy-out" and here is where you start purchasing items.
This entails drilling into the bolt shaft using a drill bit about half the diameter of the bolt shaft itself. The correct size "Easy-out" tool is then screwed into the newly made hole(it screws in counter clockwise) and as the tool grips the inside of the bolt shaft it will unscrew the bolt shaft.
A third alternative would be to drill out the bolt completely and use what is called a heli-coil to repair the hole. I doubt the last will be viable as there is not much metal to work with.
As a last resort you can purchase an aftermarket antenna and install it in a differant place on the car's bodywork.

the antenna mast has a nylon cable attached to the end of it which goes into the electric motor that raises it and lowers the mast. This cable has snapped apart causing this problem. A new mast or antenna will be needed to repair this back to working condition

You can drill out the snapped-off screw and re-tap the hole. Then just put in a new (and slightly larger) screw. You will probably need a larger screw if you drill it out past the existing threaded hole. If you're lucky, you can sometimes just push a screwdriver against the edge of the screw and rotate the screw out that way until you can grip it with pliers and unscrew it. Then just put in a new screw.

It is not Very Easy to get to But, You can access this through the Fender Holes under the Hood. Please Rate My Response! Thanks!

All you should have to do is unscrew it from the base mount on your car. the antenna itself is all that you should have to replace, not the wire.
