1. A filling level measuring device antenna cover designed to cover a horn antenna of a filling level measuring device, comprising:
- a base body;
a plurality of circular inner fins, each having the shape of a hollow cylinder, concentrically arranged on an inner surface of the base body, which inner surface faces towards an inside of the horn antenna when the cover covers the horn antenna; and
a central dome arranged on a symmetry axis of the inner fins,wherein the inner fins and the base body consist of a plastic material injected at a top of the central dome,wherein the inner fins and the dome have a common thickness,wherein the thickness of each of the inner fins is one of less than and equal to 0.7 times a thickness of the base body, the plastic material used for molding the cover solidifies at every region of the plurality of circular fins substantially simultaneously.
