US Patent 10116048 Antenna with rotatable radiating element

The invention teaches a telecommunications antenna with a housing comprising a radome (12) and a radiator (70) arranged in the housing, wherein the radiator (70) is mounted to a support structure (30) that is conductive in the electromagnetic sense, said support structure so engaging the housing that it is in either one of a rotatable fashion or a rotatably fixed fashion about and axis, in that at least one body (80) that is non-conductive in the electromagnetic sense is tensionable in a direction parallel to the axis in such a fashion that a transition from the rotatable fashion to the rotatably fixed fashion is permitted by forming a frictional engagement.
