  Um dies zu vermeiden, kann der Reflektor aus mehr als zwei Teilen zusammengesetzt werden, z. B. vier Teilen 1, 2, 3, 4, wie Fig. 3 und 4 zeigen. 



   Gemäss Fig. 4 können die Reflektorteile, also z. B. 1-4, rohrförmig sein, und die Röhren D können in Gehäusen J sitzen, die aus einem Isolierstoff bestehen. Die Röhren D sind mittels Drähte E, die in dem Reflektor   R liegen, parallelgeschaltet und können   auf diese Art an leitende Mäntel F der Reflektorteile angeschlossen sein. Die Drähte E können auch für eine Reihenschaltung der Röhren D dienen. 



   Dadurch, dass die Drähte   B   in dem Reflektor angeordnet sind, werden Feldverzerrungen vermieden. 



   Bezüglich der Strahlungscharakteristik ist die neue Anordnung besonders dann vorteilhaft, wenn die Reflektoren R Halbdipole sind, wie Fig. 5 darstellt, weil dann das Tasten in unmittelbarer Nähe der Erdoberfläche erfolgt. 



   Reflektoranordnungen gemäss der Erfindung sind leicht aufzubauen, wie sich aus den geschilderten Beispielen ergibt, und sind besonders dann für hohe Frequenzen geeignet, wenn die Reflektoren in der beschriebenen Weise aus mehr als zwei Teilen zusammengesetzt sind. 



   Die Erfindung ist in ihrer Anwendung nicht auf Funkbaken beschränkt, sondern ist bei allen Strahlungsgebilden verwendbar, die getastet werden sollen. 



   PATENT-ANSPRÜCHE :
1. Anordnung zum Tasten von Strahlungsgebilden, insbesondere Funkbaken, dadurch gekennzeichnet, dass das Zu-und Abschalten mittels   Gasentladungsröhren   geschieht.

 EMI2.1
 



  To avoid this, the reflector can be composed of more than two parts, e.g. B. four parts 1, 2, 3, 4, as Fig. 3 and 4 show.



   According to FIG. 4, the reflector parts, so z. B. 1-4, be tubular, and the tubes D can sit in housings J, which are made of an insulating material. The tubes D are connected in parallel by means of wires E which lie in the reflector R and can in this way be connected to conductive jackets F of the reflector parts. The wires E can also be used to connect the tubes D in series.



   Because the wires B are arranged in the reflector, field distortions are avoided.



   With regard to the radiation characteristics, the new arrangement is particularly advantageous when the reflectors R are half-dipoles, as FIG. 5 shows, because the keys are then in the immediate vicinity of the earth's surface.



   Reflector arrangements according to the invention are easy to set up, as can be seen from the examples described, and are particularly suitable for high frequencies when the reflectors are composed of more than two parts in the manner described.



   The application of the invention is not restricted to radio beacons, but can be used for all radiation patterns that are to be scanned.
