A feedhorn portion constitutes part of a converter, and includes a chassis body with a waveguide having an opening, a dielectric as a dielectric member connected to the opening, and a waterproof cover as a protective member. The waterproof cover covers the dielectric and contacts (tightly attached) to a portion of the surface of the dielectric (in the dielectric, the portion of the surface away from waveguide). The waterproof cover is formed of a material having substantially the same electric characteristics (permittivity and dielectric loss tangent) as the material forming the dielectric.

Abstract: A radio wave reception converter receives a radio wave and converts the radio wave into an electric signal, and includes a horn introducing a radio wave, and a waveguide arranged at the rear of the horn for guiding a radio wave introduced by the horn. An insulation sheet is located between the waveguide and the horn to seal hermetically the interior of the waveguide and the horn. The connecting part between the waveguide and the horn is covered with an exterior cabinet. The front opening of the horn is covered with a feedome. The structure facilitates the connecting work between the waveguide and the horn, and can ensure airtightness at the connecting part.
