Abstract

Es wird eine Antenne mit parabolischem Reflektor und mindestens einer Speiseleitung angegeben, an deren freiem Ende ein Erreger angebracht ist. In einer zentralen Öffnung des Reflektors ist eine die Öffnung verschließende, als Kreisscheibe ausgeführte Halteplatte (7) angebracht, in welcher die Speiseleitung befestigt ist. Zur verkantungsfreien Drehbarkeit der Halteplatte (7) im Reflektor ist in deren Umfangsfläche mindestens eine in Umfangsrichtung verlaufende Nut angebracht. In die Nut greifen mindestens drei um 120° in Umfangsrichtung gegeneinander versetzte und in radialer Richtung verlaufende Stifte (9) ein, die in einem die Halteplatte (7) umgebenden und am Reflektor befestigten Ring (8) angebracht sind.
