Abstract
A fill level measuring device working with microwaves, having an antenna for transmitting, or for transmitting and receiving, microwaves. The antenna has a metallic outer conductor and a ceramic inner conductor. The inner conductor is secured in a pressure-tight and gas-sealed manner in the outer conductor. A coating of a fluorothermoplastic is provided on the inner conductor or in the outer conductor. The inner conductor is secured in the outer conductor by means of a warm-pressed fit, and the inner conductor and the outer conductor have conical surfaces of equal shape in the region of the pressed fit.
