Abstract

Claims (19)

1. A telecommunications antenna with a housing comprising a radome and a radiator arranged in the housing, wherein the radiator is mounted on an electroconductive support structure, wherein the electroconductive support structure engages the housing in either one of a rotatable fashion or in a rotatably fixed fashion about an axis through at least one non-electroconductive body and is tensionable in a direction parallel to the axis so that a transition from the rotatable fashion to the rotatably fixed fashion is effected by forming a frictional engagement,

wherein the non-electroconductive body is a clamping body and

wherein the non-electroconductive body is tensionable by a fastener engaging in a non-electroconductive bracket section.

2. The telecommunications antenna according to claim 1 , wherein the housing comprises further said non-electroconductive bracket section.

3. The telecommunications antenna according to claim 1 , wherein the electroconductive support structure is configured to be pot-shaped.

4. The telecommunications antenna cording to claim 3 , wherein the electroconductive support structure has a cylindrical wall that extends with reference to the axis over a length of at least λ/20, wherein λ is the average operating frequency of the telecommunications antenna.

5. The telecommunications antenna according to claim 1 , wherein the electroconductive support structure has an annular protruding edge configured to be engaged with a groove in the housing.

6. The telecommunications antenna according to claim 1 , wherein the electroconductive support structure engages the housing via an O-ring.

7. The telecommunications antenna according claim 1 , comprising at least one non-electroconductive spacing element between the radiator and at least one of the electroconductive support structure and the radome.

8. The telecommunications antenna according to claim 1 , wherein the support structure comprises at least one of a rotation aid, an angular indication and an angular indexing.

9. The telecommunications antenna according claim 1 , wherein the fastener has a terminal end that terminates short of an end of the electroconductive support structure so that the fastener does not extend beyond the electroconductive support structure in the direction of the radiator.

10. The telecommunications antenna according to claim 1 wherein the non-electroconductive body is constructed as a claw with two legs.

11. The telecommunications antenna according to claim 10 , wherein the claw is provided with biasing sections at its ends.

12. The telecommunications antenna according to claim 11 , wherein the biasing sections protrude by around 0.6 mm beyond a reference plane, defined adjacent a fastener for tensioning the non-electroconductive body.

13. The telecommunications antenna according to claim 10 , wherein, in a base area of the two legs, the claw has one of a protrusion or a biasing section protruding beyond a reference plane by around 0.2 mm, as defined adjacent to a fastener for tensioning the non-electroconductive body.

14. The telecommunications antenna according to claim 1 , wherein the housing is executed cylindrically at least in the area of the radiator.

15. The telecommunications antenna according to claim 1 , further comprising a pressure-responsive element.

16. The telecommunications antenna according to claim 1 , further comprising at least one of a securing element or a guide in axial direction for the non-electroconductive body.

17. The telecommunications antenna according to claim 1 , wherein two of the radiators are mounted on two electroconductive support structures disposed on respective distal sections of the radome and are executed in particular as similar parts.
