A screwable vehicle antenna has a threaded part and a head part, which adjoins an end region of the threaded part. The threaded part and the head part both are made of electrically non-conductive material. At least one antenna radiator is arranged at least within part of the head part. A metal disk made of electrically conductive material is arranged on the head part and is used as a reflector or a ground plane. An HF electrical connector is provided, which is arranged on and fastened to a region of the head part remote from the threaded part, and the antenna radiator can be electrically connected to a plug of the HF electrical connector.
