A broadband omnidirectional antenna comprises a first radiator which is galvanically isolated from a base plate and extends away therefrom. The first radiator has a first end comprising a foot and/or feed-in point and a second end which is opposite the first end, and radiator surfaces which originate in the region of the first end and extend towards the second end. A second radiator comprises at least one radiator surface, the second radiator being arranged on the first radiator so as to be galvanically isolated therefrom. It is possible for said second radiator to be fed exclusively by the first radiator. The radiator surfaces of the second radiator are arranged as a continuation of the first radiator or the at least one radiator surface of the second radiator is arranged in the region of the second end of the first radiator so as to be in parallel with the base plate.

Broadband omnidirectional antenna

The invention teaches a telecommunications antenna with a housing comprising a radome () and a radiator () arranged in the housing, wherein the radiator () is mounted to a support structure () 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 () 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.
