Can you help me fix this?

[MyFamilyAndOtherAnimals1]

I've broken my lovely-little-yellow car's radio-aerial (see pic !) and am struggling to hear my eclectic mix of the Archers and Radio 1

However, I believe it should be quite easy to fix by myself??!!

...do any of you have any suggestions how I should do this?

Should I just plier it open and jam another piece of metal in there?
Or, do you think I'll need to start flexing my lady-muscles, and get out a pink screw-driver?

Buy a replacement aerial then unscrew the top and put the new part in by the look of it. Some aerials screw on so it might be a case of unscrewing what it left (turn it to the left). You may need pliers to give enough purchase.

Thanks @wowfudge ! I'll give that a go!

My post is unclear: you may just need to manually unscrew what is left of the aerial and fit a new one. Or, you may need to undo both the screws, remove the plastic cover and fit the new aerial.
