Description

Anordnung zur Verbesserung der Ausstrahlung in den Raum, insbesondere bei Kurzwellengeräten. Es ist bekannt, daß die Ausstrahlung einer Sendeanlage mit der Güte der Erdung wächst und ferner, daß die Ausstrahlung einer gegebenen Antennenanlage, insbesondere bei Kurzwellengeräten, unter einem um so stumpferen Winkel zur Erdoberfläche erfolgt, je besser das Leitvermögen der Erdfläche ist. Bekannte Untersuchungen darüber haben ergeben, daß die optimale Strahlung unter einer Elevation von 45 bis 70° stattfindet, wenn dabei die Antenne auf ein Vielfaches der Erregerwelle abgestimmt wird.Arrangement to improve the appearance in the room, in particular with shortwave devices. It is known that broadcasting a transmitter with the quality of the earthing increases and furthermore that the radiation of a given antenna system, especially with shortwave devices, at an all the more obtuse angle to the earth's surface occurs, the better the conductivity of the earth's surface. Well-known studies about it have shown that the optimal radiation takes place at an elevation of 45 to 70 °, if the antenna is tuned to a multiple of the exciter wave.

Gemäß der vorliegenden Erfindung wird daher, um die Strahlung eines für kurze Wellen verwendeten isolierten Dipoles möglichst nach oben zu richten, das bei gewöhnlicher Erde nicht vorhandene gute Leitvermögen der Erdfläche auf künstlichem Wege hergestellt. Unterhalb des isolierten Dipols wird eine mit dem Dipol nicht verbundene leitende Schicht durch Belegen der Erdfläche mit einem leitenden Stoff erzielt. Diese Belegung kann ein in sich geschlossenes homogenes Ganzes bilden oder auch nach Art der bekannten Erdungsanlagen aus einem Drahtstern, Drahtnetz, metallischer Gase, Metallspänen o. dgl. bestehen. Man kann auch das Leitvermögen der Erdfläche auf die gewünschte Güte dadurch bringen, daß die Erdoberfläche mit Stoffen getränkt wird, die entweder für sich leitend sind oder durch ihre chemische Verbindung mit den Erdstoffen leitend werden. Die mit einer künstlich so erzeugten leitenden Schicht angestellten Versuche haben ergeben, daß das beste Resultat bei einer Fläche erzielt wird, deren Radius etwa das Drei- bis Vierfache einer Wellenlänge beträgt.According to the present invention is therefore to the radiation a to direct the isolated dipoles used for short waves upwards as far as possible, the good conductivity of the surface of the earth which does not exist with ordinary earth on artificial ones Paths made. Below the isolated dipole, one with the dipole will not connected conductive layer by covering the earth's surface with a conductive substance achieved. This occupancy can form a self-contained, homogeneous whole or also in the manner of the known earthing systems made of a wire star, wire mesh, metallic Gases, metal chips or the like exist. One can also measure the conductivity of the earth's surface bring to the desired quality by soaking the earth's surface with substances which are either conductive in themselves or through their chemical connection with become conductive to the earth. The one with an artificially created conductive layer Attempts made have shown that the best result is achieved with a surface whose radius is about three to four times a wavelength.
