Description
<Desc/Clms Page number 1>
Anordnung zum Richtempfang von kurzen Wellen.
Zum Goniometerempfang von normal polarisierten Wellen, d. h. von Wellen, deren magnetische Feldstärke parallel zur Erdoberfläche verläuft, werden bekanntlich zwei zueinander senkrecht stehende Rahmen, deren Fläche senkrecht zur Erdoberfläche steht, verwendet. Es ist anzunehmen, dass bei kurzen Wellen eine Drehung der Polarisationsebene eintritt, so dass dann auch mit einer Komponente der Feldstärke zu rechnen ist, die normal zur Erdoberfläche steht. Für diesen Fall reicht die Anordnung mit zwei Rahmen nicht mehr aus, um das Maximum des Empfangs zu erzielen. Gemäss der Erfindung wird diese durch eine Anordnung möglich, bei der man ausser den zwei Rahmen mit senkrechter Windungsfl che einen dritten mit horizontaler Windungsfläche verwendet.
Zu den Feldspulen im Goniometer müssen dann noch eine oder zwei horizontale hinzutreten, und die Drehspule muss ausser um die vertikale Achse noch um eine horizontale Achse drehbar gemacht werden.
Man kann auch, um den horizontalen Rahmeneffekt zu empfangen, noch eine besondere Kopplungsspule verwenden, die mit der Drehspule des Goniometers in Serie liegt.

Arrangement for directional reception of short waves.
For goniometer reception of normally polarized waves, i. H. of waves whose magnetic field strength runs parallel to the earth's surface, two frames are used, which are perpendicular to one another and whose surface is perpendicular to the earth's surface. It can be assumed that with short waves a rotation of the polarization plane occurs, so that a component of the field strength that is normal to the earth's surface must then be expected. In this case, the arrangement with two frames is no longer sufficient to achieve the maximum reception. According to the invention, this is made possible by an arrangement in which, in addition to the two frames with a vertical winding surface, a third frame with a horizontal winding surface is used.
One or two horizontal coils must then be added to the field coils in the goniometer, and the rotating coil must be made rotatable around a horizontal axis in addition to the vertical axis.
In order to receive the horizontal frame effect, a special coupling coil can also be used, which is in series with the rotating coil of the goniometer.
