描述
Deutsch: Die größte Erdfunkstelle der Welt bei Raisting (in der Nähe des Ammersees) ist eine Bodenstation für die Kommunikation mit Nachrichtensatelliten und ist mit ihren großen Parabolantennen weithin sichtbar.
English: A parabolic satellite communication antenna at the biggest facility for satellite communication in Raisting, Bavaria, Germany. This type of parabolic antenna is called a Cassegrain antenna. The radio waves emerge from the hole in the center of the dish and are focussed on a convex subreflector suspended on the supports in front of the dish. The waves are reflected back toward the main dish, which reflects them forward to form the outgoing beam aimed at the satellite.
Français : Le plus gros centre de communication satellitaire à Raisting, en Bavière (Allemagne).
