Description
Antennengebilde mi evorzugter Bodenstrahlung Zusatz zu'i P,ttLflt 6S0 912 Im Hauptpatent wird ein Antennengebi ide vorgeschlagen, das aus einem senkrechten, im Schwingungsschwerpunkt durch eine Spule verlängerten Dipol besteht, dessen Schwingungsschwerpunkt von der Erde aus gerechnet den Abstand i besitzt und daß das untere Ende des Dipols so hoch über dem Erdboden liegt, daß ein störendes Erdfeld nicht auftreten kann.Antenna structure with preferential ground radiation addition to'i P, ttLflt 6S0 912 In the main patent, an antenna area is proposed that consists of a vertical, there is a dipole lengthened by a coil in the center of vibration, whose center of vibration calculated from the earth has the distance i and that the lower end of the dipole is so high above the ground that an interfering earth field cannot occur.
Es wurde nun im Hauptpatent vorgeschlagen, zur Speisung dieses Dipols insbesondere Energieleitungen bekannter Art vorzusehen. It has now been proposed in the main patent to feed this dipole in particular to provide power lines of a known type.
Bei der praktischen Durchführung derartiger Anordnungen ergaben sich jedoch gewisse Schwierigkeiten, da die Abstimmung und die evtl. Stromkontrolle der Dipolhälften hoch oben in der Luft (an einem Turm) und nicht auf der Erde, also einer nicht leicht zugänglichen Stelle, vorgenommen werden muß.In the practical implementation of such arrangements resulted however, certain difficulties, since the coordination and the possible current control of the Dipole halves high up in the air (on a tower) and not on earth, so a place that is not easily accessible.
Es wird deshalb erfindungsgemäß vorgeschlagen, die Abstimmung und Erregung des Dipols in an sich bekannter Weise mittels einer Doppelleitung vom Erdboden aus vorzunehmen. It is therefore proposed according to the invention, the vote and Excitation of the dipole in a manner known per se by means of a double line from the ground off.
In der beiliegenden Abbildung ist schematisch die Ausführungsform der erfindungsgemäßen Einrichtung dargestellt. Im Fall der Abbildung ist ein schematischer Dipol zwischen zwei Masten verspannt. Der Dipol besteht aus zwei Hälften Di. An den voneinan der abgekehrten Enden der Dipolhälften sind waagerechte Belastungsstücke B vorgesehen, durch welche bei einer Verkürzung des Dipols gegenüber 44 eine entsprechende Stromverschiebung erzielt wird. Die waagerechten Stücke sind nach den Masten M verspannt. Die Abstimmung und Erregung des ganzen Systems erfolgt mittels der L)oI>pelleitung, und L2 in an sich bekannter Art. The embodiment is schematically shown in the accompanying figure the device according to the invention shown. In the case of the figure is a schematic Dipole clamped between two masts. The dipole consists of two halves Di. An the ends of the dipole halves facing away from one another are horizontal loading pieces B is provided, through which, when the dipole is shortened compared to 44, a corresponding Current shift is achieved. The horizontal pieces are braced after the masts M. The coordination and excitation of the entire system takes place by means of the L) oI> p line, and L2 in a manner known per se.
Die erfindungsgemäße Anordnung hat den Vorteil, daß vom Boden aus die Abstimmung des Systems und seiner Stromverhältnisse überwacht werden kann, da es genügt, in den Leitungen L1 und L0 bzw. in den Abstimm-oder Kopplungskreisen Meßinstrumente anzuordnen. Hat man jedoch, wie im Hauptpatent vorgeschlagen, eine Energieleitung, die stromgekoppelt ist, so sind in den Dipolen selbst oben am Mast Abstimmittel und Meßinstrumente notwendig, die man von unten durch Fernsteuerung betätigen bzw. mit einem Fernrohr ablesen kann. Man kann auch besondere Meßleitungen verwenden, um die Ableseinstrumente selbst unten anbringen zu können. The arrangement according to the invention has the advantage that from the ground the coordination of the system and its current conditions can be monitored because it is sufficient in lines L1 and L0 or in the tuning or coupling circuits To arrange measuring instruments. However, as suggested in the main patent, one Power lines that are electrically coupled are in the dipoles themselves at the top of the mast Tuning means and measuring instruments are necessary, which can be remote-controlled from below can be operated or read with a telescope. You can also use special test leads to be able to attach the reading instruments yourself at the bottom.
Sowohl die Fernbetätigung als auch die Fernablesung benötigen besondere zusätzliche Leitungen, die u. U. unangenehm sein können, da sie, wenn nicht besondere Maßahmen getroffen sind, das Strahlungsdiagramm beeinflussen.Both remote control and remote reading require special additional lines that may be uncomfortable because they, if not special Measures are taken that affect the radiation pattern.
