Abstract
A mobile antenna that repeatably can be attached and detached by rotation from motor vehicles. The antenna having a receiving portion electrically connected to a base body having a contact area for connecting to motor vehicles. The joined base body and receiving portion being encased in a jacket. The base body having grooves with flank surfaces also encased in the jacket; the grooves aligned in the lengthwise direction of the antenna so that the groove flank surfaces are essentially perpendicular to forces produced when the jacket is rotated for attachment and detachment of the antenna to or from the motor vehicle.
Claims8
An antenna that by rotation of said antenna can be attached and detached from a structure, said antenna comprising:
- a base body with a contact area disposed to be in electrical contact with said structure when said antenna is attached to said structure;
- a receiving portion in electrical contact with said base body;
- said base body and said receiving portion being encased in a jacket;
- and
- at least two flank surfaces provided on said base body and said flank surfaces being encased by said jacket,
- wherein a force produced when said jacket is rotated in one direction acts in an essentially perpendicular arrangement from said jacket against at least one of said flank surfaces and when said jacket is rotated in an opposite direction another force acts in an essentially perpendicular arrangement from said jacket against at least another of said flank surfaces.
