English: Fan beam antenna pattern can be a result of a cropped parabolic dish: the longer dimension of the parabolic remnant make a narrower beamwith in this dimension.

Deutsch: Das Diagramm einer Fan-Beam-Antenne kann durch einen unsymmetrischen Ausschnitt einer Parabolantenne erzeugt werden. Generell gilt: die Ebene mit der größeren Ausdehnung bewirkt ein schmaleres Diagramm. Das gezeigte Beispiel ist die obere Antenne des russischen Radargerätes P–37 "Bar Lock". Dessen Antennendiagramm wird als 1,5° im Azimut und mehr als 15° im Höhenwinkel genannt. |
