Antenna Cable Stripped

Anyone know where I can get a new antenna cable with the body that allows you to thread in any aftermarket antenna? Mine is stripped and I can’t thread anything in, even with thread seal tape. I’m thinking the actual thread insert might have snapped off inside but regardless it would be nice to replace.
Here’s a picture of what it looks like currently.

To me it looks like the metal connector is gone from the end of the cable and this piece is not the factory antenna. Isn’t this cable plugged into another cable down in the fender/trunk section of your car. Here is a link to a good complete replacement power antenna at Parts-Express: https://www.parts-express.com/Metra-44-PW22-Universal-Car-Radio-Power-Antenna-265-951 . Here is a short piece of car antenna cable with the male and female ends shown:

I would think that the cable shown in your picture has an end like one of the ones in my picture.
