Pulled out my antenna cord. Now what?

Probably just broke the copper center conductor off inside the skinny part of the plug.

You can heat the tip of the plug up with a solder iron and while the solder is still liquid bang it quickly on your workbench and the broken part will probably drop out. You’ll see the skinny end has a hole in it.

Then just roll the shield back, strip a little of the insulation off the center conductor, stick it back up in your plug until you see the center conductor come out the hole in the skinny end of the plug.

Solder the center conductor back to the tip of the plug and you’re good to go. It’s an easy fix!
