2017 Ram broken arial

[Northermonkee]

I checked for a thread and couldn’t find one. Apologies if this has been posted before. I broke my arial off in the car wash and ordered a smaller arial to screw on and there isn’t any thread connector to screw onto . Any advice very welcome.
Many thanks,
Rob

Perhaps it broke the stud? It's a double ended threaded fitting that attaches the antenna base to the mast. Post a picture of what you see.
