Hep with a little problem?

For a telescopic antenna for a fm radio, what do u call the end the screws on to the end of the antenna
Update: Where can i find the ones with the end to screw on the end of the antenna? not the rf end but the screw hole end.
Update 3: looking for an end connection like this with the screw attachment https://imgsafe.org/image/98a0e22e9e
