Description

Feststehendes Antennensystem mit schwenkbarer Richtcharakteristik Für. die Sicherstellung eines einwandfreien UKW- und Fernsehempfanges sind Antennen mit guter Bündelung erforderlich. Diese läßt sich nur mit verhältnismäßig großen Abmessungen der Antennenanordnung erzielen. Die Ausrichtung derartiger Richtantennen auf den jeweils zu empfangenden Sender ergibt Schwierigkeiten, die nur mit einem erheblichen technischen Aufwand zu überwinden sind.Fixed antenna system with swiveling directional characteristic For. Antennas ensure perfect FM and television reception with good bundling required. This can only be achieved with relatively large Achieve dimensions of the antenna assembly. The alignment of such directional antennas on each station to be received results in difficulties with only one considerable technical effort must be overcome.

Eine wesentliche Verminderung der genannten Schwierigkeiten wurde durch eine Verwendung von feststehenden Antennensystemen mit schwenkbarer Richtcharakteristik erreicht. Bei diesen werden mit Hilfe eines Umschalters - gegebenenfalls eines fern zu bedienenden - die einzelnen Antennenelemente derart zu Primär- und Sekundärstrahlern verbunden, daß sich die gewünschte Strahl- bzw. Empfangsrichtung ergibt.A substantial alleviation of the aforementioned difficulties was made through the use of fixed antenna systems with swiveling directional characteristics achieved. With the help of a toggle switch - if necessary one remote to be operated - the individual antenna elements in this way to primary and secondary radiators connected that results in the desired beam or receiving direction.

Bei den Antennensystemen dieser Art muß der Bedienende bei jedem Stationswechsel außer der Einstellung des Empfängers auf die zu empfangende Frequenz jedesmal auch die Empfangsrichtung der Antenne erneut einstellen.With antenna systems of this type, the operator has to change each station apart from setting the receiver to the frequency to be received each time too adjust the reception direction of the antenna again.

Erfindungsgemäß wird die Empfängerbedienung dadurch wesentlich erleichtert, daß der Fernbedienungssehalter für die Umschaltung der Antennenelemente derart mit dem Kanalwähler des Empfangsgerätes gekoppelt ist, daß die Richtcharakteristik selbsttätig auf die Einfallsrichtung der dem jeweils eingeschalteten Kanal entsprechenden Strahlung eingestellt wird.According to the invention, the operation of the receiver is made much easier by that the remote control switch for switching the antenna elements with such the channel selector of the receiving device is coupled that the directional characteristic automatically on the direction of incidence of the radiation corresponding to the respective switched-on channel is set.

Die erfindungsgemäße Anordnung erweist sich besonders bei solchen Empfängern vorteilhaft, bei denen wahlweise bestimmte Übertragungskanäle; die zumindest grob vorabgestimmt sind, eingeschaltet werden können, wie dies z. B. bei den meisten gebräuchlichen Fernsehempfängern der Fall ist.The arrangement according to the invention proves particularly in such Beneficiaries, in which optionally certain transmission channels; at least that are roughly pre-agreed, can be switched on, as z. B. with most common television receivers is the case.

Während also bei den bisher bekannten mit Richtantennen versehenen Empfangseinrichtungen immer sowohl die Empfangsfrequenz als auch die Empfangsrichtung eingestellt werden mußte, braucht bei der erfindungsgemäßen Einrichtung die Richtung der Antenne an einem Empfangsort nur einmal für jeden Kanal eingestellt zu .werden, .um sich dann wegen der vorhandenen Kopplung zwischen Kanalwähler und Fernbedienungsschalter selbsttätig auf die jedem Kanal entsprechende Empfangsrichtung. einzustellen, solange senderseitig keine Änderungen der Frequenz oder des Aufstellungsortes vorgenommen werden. Dadurch wird nicht nur der Bedienungskomfort erhöht, sondern auch die Möglichkeit einer falschen Einstellung der Antennenrichtung zwangläufig vermieden.So while with the previously known with directional antennas Receiving devices always both the receiving frequency and the receiving direction had to be set, needs the direction in the device according to the invention the antenna can only be set once for each channel at a receiving location, .to then because of the existing coupling between the channel selector and the remote control switch automatically to the receiving direction corresponding to each channel. set as long as No changes to the frequency or the installation site have been made on the transmitter side will. This not only increases the ease of use, but also the possibility an incorrect setting of the antenna direction is inevitably avoided.
