Abstract:
The invention relates to an apparatus (1) for ascertaining and monitoring fill level (2) of a medium (3) in a container (4) by means of a travel-time measuring method of high-frequency measurement signals (6) with a horn antenna (7) having a waveguide section (8), a flared, horn section (9) and a cavity (11) filled, at least partially, with a dielectric filling body (12). Object of the invention is to provide a simple, temperature-stable, horn antenna filled with a dielectric material.
