Description

Das Strahlungsdiagramm eines Strahlers kann durch zusätzliche Strahler zu einem Richtdiagramm verformt werden. Zu diesem Zweck benutzt man einen oder mehrere Strahler als Reflektoren und/oder Direktoren. Durch Wahl der Strahlerlängen, des Abstandes der zusätzlichen Strahler untereinander und vom Hauptstrahler und durch geeignete Abstimmittel und gegebenenfalls Speisung kann man das Strahlungsdiagramm der gesamten Anordnung in bekannter Weise beeinflussen.The radiation pattern of a radiator can be achieved with additional radiators can be deformed into a directional diagram. One or more are used for this purpose Spotlights as reflectors and / or directors. By choosing the lamp lengths, des Distance of the additional radiators from each other and from the main radiator and through Suitable tuning means and, if necessary, feeding can be used in the radiation diagram affect the entire arrangement in a known manner.

Derartige Anordnungen werden aber besonders dann sehr aufwendig, wenn es sich nicht um sehr kurze, sondern um mittlere und lange Wellen handelt, bei denen die Strahler aus verspannten Masten bestehen.Such arrangements are very expensive especially when the waves are medium and long, rather than very short, where the spotlights consist of braced masts.

Die Erfindung zeigt nun einen Weg, den Aufwand für die Bildung von Strahlungsrichtdiagrainmen dadurch zu vermindern, daß die Mastverspannungen als zusätzliche Strahler herangezogen werden. Gemäß der Erfindung werden bei einem verspannten Antennenmast seine Verspannungen als Reflektoren und/oder Direktoren verwandt.The invention now shows a way of reducing the effort for the formation of To reduce radiation direction diagrams that the mast tensions as additional radiators can be used. According to the invention, a braced Antenna mast related its tension as reflectors and / or directors.

Die Fig. i und a zeigen Ausführungsbeispiele, die sich mit an sich bekannten Mitteln weitgehend abändern lassen. In der Fig. i wird der Antennenmast i, der auf dem Isolator :2 steht; durch die Abstimmittel 3 und q. abgestimmt und über die Koppeleinrichtung 5 vom Sender 6 gespeist. Die eine eingezeichnete Verspannung 7 ist durch Isolatoren so unterteilt, daß die verbleibenden kleinen Leiter keinen merklichen Einfluß auf das Strahlungsdiagramm haben. Die andere eingezeichnete Verspannung ist dagegen auf eine größere Länge 8 nicht durch Isolatoren unterteilt und wird durch die Abstimmittel 9 und- io so abgestimmt, daß sie als passiver Reflektor wirkt. .Figs. I and a show embodiments that are inherent in have known means largely changed. In Fig. I the antenna mast i, which stands on the insulator: 2; by the tuning means 3 and q. matched and Fed via the coupling device 5 from the transmitter 6. The one drawn tension 7 is divided by insulators so that the remaining small conductors do not have any have a noticeable influence on the radiation pattern. The other drawn tension is, however, not divided over a greater length 8 by insulators and is tuned by the tuning means 9 and io so that it acts as a passive reflector. .

Die Bezeichnungen in Fig. a entsprechen bezüglich. der Speisung des Mastes ünd bezüglich der rechten Verspannung. und der zugehörigen Abstimmittel den Bezeichnungen von Fig. i. Die linke Verspannung i i ist ebenfalls auf eine größere Länge nicht durch Isolatoren unterteilt und durch Abstimmittel 1a und 13 'so abgestimmt, daß diese Verspannung als Direktor wirkt.The designations in Fig. A correspond with respect to. the feeding of the Mastes and regarding the right bracing. and the associated voting means Designations of Fig. I. The left tension i i is also on a larger one Length not subdivided by isolators and matched by tuning means 1a and 13 'so that that this tension acts as a director.

In gleicher Weise lassen sich die Verspannungen auch als gespeiste zusätzliche Strahler verwenden.In the same way, the tensions can also be fed use additional emitters.
