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.

1-12. (canceled)
An apparatus for ascertaining and monitoring the fill level of a medium in a container by means of a travel-time measuring method of high-frequency measuring signals, comprising:
- a horn antenna having a waveguide section, a flared, horn section, and a cavity filled, at least partially, with a dielectric filling body, wherein:
- a defined separation is provided in said flared, horn section between the inner surface of said horn antenna and the outer surface of said dielectric filling body for compensating different thermal expansions of said dielectric filling body and said horn antenna.
