A filling level measuring device operating with microwaves and to be fastened on a container (3) is provided, the device having a housing (11) and a rod-shaped antenna (7) pointing into the container (3) and the device being designed such that the antenna (7) does not transmit or receive microwaves in the region of a measuring device fastening and the transmitted power is not impaired by condensate or moisture. According to a first solution variant, the antenna (7) is fastened in the housing (11) and a section of the antenna (7) in the region of the measuring device fastening is surrounded by a metallic sleeve (8). According to a second solution variant, a sleeve (8a) in which the antenna (7) is fastened is formed onto the housing (11).

[ What is claimed is:] [1.]1. A method of producing a filling level measuring device operating with microwaves that is to be fastened onto an upper end of a connection piece that is mounted at a lower end thereof to an opening of a container, comprising the steps of:forming a housing of the filling level measuring device such that the housing is configured to be mounted to the upper end of the connection piece;forming an antenna of the filling level measuring device from a dielectric material;fastening the antenna to the housing such that the antenna points into the opening of the container when the housing is mounted to the upper end of the connection piece, andforming a metallic sleeve over said antenna such that said metallic sleeve tightly encloses the antenna from the housing to the opening of the container when the housing is mounted to the upper end of the connection piece.
