  • the screw thread 15 is part of a Antenna base 10 of the rod antenna 1.
  • the antenna base 10 has a rotatable slip clutch 20, so with the Screw thread 15 cooperates that by a rotary movement the slip clutch 20 a rotation of the screw thread 15 he follows. This can be done as shown in the example in FIG. 1 the slip clutch 20 coaxial with the screw thread 15 in Antenna base 10 provided and fixed with the axis of rotation 25 be connected to the screw thread 15.
  • the antenna base 10 further comprises a rotating body 30 which is concentric with the Axis of rotation 25 the antenna rod 35 in which the Fastening surface 5 facing part of the rod antenna 1 envelops.
  • the slip clutch 20 is thereby from the rotating body 30 covered with elastic.
  • the rod antenna 1 is screwed onto the mounting surface 5 as follows: The rotating body 30 is rotated in the direction of rotation required for screwing the antenna rod 35 to the mounting surface 5, whereby the sliding clutch 20 is carried along by the rotating body 30 by the elastic covering of the slip clutch 20 and the screw 45 with the screw thread 15 in the Screwing the antenna rod 35 to the mounting surface 5 rotates the required direction.
  • the bolt 45 can thus be screwed into the screw opening 50.
  • a loosening of the rod antenna 1 from the mounting surface 5 is possible by a corresponding rotary movement of the antenna rod 35, which is firmly connected to the screw thread 15 via the axis of rotation 25, at the locations of the antenna rod 35 that are not enclosed by the rotating body 30.
  • the diameter of the antenna rod 35 is significantly smaller than that of the rotating body 30, especially in the area of the slip clutch 20, an increased effort is required for such a release of the rod antenna 1 from the fastening surface 5.
  • This process of detaching the rod antenna 1 from the fastening surface 5 is further complicated if the antenna rod 35 has a metallic surface that is not as easy to grip as, for example, a plastic surface of the rotating body 30.
  • FIG. 2 shows a cross section of the slip clutch 20 perpendicular to the axis of rotation 25 according to a first Embodiment.
  • the elastic is also shown Envelope of the slip clutch 20 by the rotating body 30, the in that the rotating body 30 in the area of Slipping clutch 20 has elastic material on the Slip clutch 20 is present.
  • the slip clutch 20 has one Wreath of teeth 55, which are sawtooth-shaped against the Direction of rotation for screwing the antenna rod 35 to the Mounting surface 5 are curved, this direction of rotation is marked by an arrow in Figure 2.
  • the elastic Material of the rotating body 30 lies on the tips of the teeth 55 on.
  • the rotating body 30 in the direction of rotation Screw the antenna rod 35 to the Fastening surface 5 moves, the teeth 55 hook in elastic material of the rotating body 30 and the Slip clutch 20 can with the rotating body 30 in this Direction of rotation.
