Description

Antennenankopplung für Peilzwecke Für Peilzwecke ist es zur Richtungsbestimmung bekannt, eine Hochantenne und einen Rahmen gleichzeitig zu benutzen. Es ergibt sich hierbei als Charakteristik die bekannte Kardioide. Die Hochantenne wird hierbei .induktiv oder kapazitiv mit dem Empfänger und dem Rahmen gekoppelt. Da die Hochantenne bei diesen Anordnungen selbst nicht abgestimmt ist, ergibt sich der Nachteil, daß Störsender, die in der Frequenz sehr von der Empfangsfrequenz abweichen, trotzdem mit aufgenommen werden und die Richtungsbestimmung erschweren, wenn nicht gar unmöglich machen.Antenna coupling for DF purposes For DF purposes it is used to determine the direction known to use a high antenna and a frame at the same time. It surrenders here as a characteristic the well-known cardioid. The aerial is here .inductively or capacitively coupled to the receiver and the frame. Because the aerial is not matched in these arrangements itself, there is the disadvantage that Jammers, which differ in frequency very much from the receiving frequency, nevertheless be included and make it difficult, if not impossible, to determine the direction do.

Vorliegende Erfindung vermeidet diese Nachte le dadurch, daß als Kopplungsspulen solche mit Hochfrequenzeisenkern benutzt werden, die so fest gekuppelt sind, daß durch die Abstimmung des Empfängerkreises eine Mitnahme des- Hochantennenkrneises erfolgt, der dadurch in gewissen Grenzen mit abgestimmt wird, ohne daß die Bedienung irgendwie erschwert wird.The present invention avoids these Nachte le in that as coupling coils those with high frequency iron core are used that are so tightly coupled that through the vote of the group of recipients a take along of the high antenna circle takes place, which is thereby coordinated within certain limits, without the operation is made more difficult somehow.

In der Abbildung ist eine beispielsweise Ausführung der Erfindung gezeigt. Es bedeutet R den Rahmen, H die Hochantenne, Li die Gitterspule des Empfängers, L@ die Kopplungsspule des Rahmens, L3 die kopplungsspule der Hochantenne. Der gemeinsame Hochfrequenzeisenkern ist durch Fe angedeutet. Es hat sich gezeigt, daß Störsender, die der Empfangsfrequenz nicht sehr benachbart sind, durch diese Kopplungsanordnung ausgeschaltet werden. Durch die Verwendung eines Eisenkernes ist eine außerordentlich feste Kopplung zwischen den drei Spulen erreicht, was bei Verwendung von Luftspulen nicht zu erzielen wäre.The figure shows an example embodiment of the invention shown. It means R the frame, H the high antenna, Li the lattice coil of the receiver, L @ the coupling coil of the frame, L3 the coupling coil of the aerial antenna. The common one The high frequency iron core is indicated by Fe. It has been shown that jammers, which are not very close to the reception frequency, due to this coupling arrangement turned off. The use of an iron core makes one extraordinary Fixed coupling between the three coils is achieved, which is what happens when using air-core coils could not be achieved.
