    • A device for receiving/transmitting electromagnetic signals from/to at least two satellites fixedly located at points at the geostationary path comprises an antenna, for example a lens (1) of waveguide nature. The antenna images remote points at a focal surface and in the points where the satellites are imaged receiver horns (23, 23') are placed. The horns are adjustably mounted to a rail (21) of a mounting unit (9) except the central horn (23') that is fixedly placed for receiving along the optical axis of the antenna, at a predetermined distance of the antenna. The rail is mounted to be rotated about the optical axis of the antenna, this giving a simple adjustment of the other horns (23). Using an adjusting assemby the curvature of the rail can be varied to be adapted to receiving at different latitudes.

    • The invention concerns a reflector and a satellite antenna system comprising such a reflector. In the satellite antenna system, microwave radiation from one or more feed horns (5) is emitted at the reflector (1), which comprises first and second reflector elements (2, 3). Upon reflection of the radiation from the reflector elements (2, 3), a distinct beam shape for the reflected microwave energy is generated. The reflector elements (2, 3) are disposed at a fixed distance from one another so that radiation that passes the first reflector element (2) strikes the second element. The first reflector element (2) comprises a lattice structure aimed toward the feed horn, which lattice structure consists of plates (8) of electrically conductive material, wherein the distance between the plates and the depth of said plates are adapted for reflection of polarization parallel to the plates. The invention is characterized in that the extent of each respective plate toward the second reflector element is chosen so that the transmission losses in the first reflector element are minimized.
