Description
Antennengebilde mit vorzugsweise allseitiger Bodenstrahlung Im Hauptpatent wird vorgeschlagen, einen am Schwingungsschwerpunkt durch eine Spule verlängerten senkrechten Dipol, dessen. Sc hwingungsschwerpunkt, von der elektrischen Erde aus gerechnet, den Abstand 7. .1 besitzt und dessen unteres Ende so hoch üb°r dem Erdboden liegt, daß ein störendes Erdfeld nicht auftreten kann, anzuordnen, um hierdurch die Bodenstrahlung gegenüber der Raumstrahlung zu bevorzugen. Es wird .auch gleichzeitig der Vorschlag gemacht, von dem Abstand ,'.l etwas abzuweichen, um hierdurch vor allem an Mastkosten zu sparen.Antenna structure with preferably all-round ground radiation In the main patent it is proposed that one be extended by a coil at the center of vibration vertical dipole, whose. Vibration center of gravity, from electrical earth calculated, the distance 7. .1 has and its lower end so high above the ground lies that a disturbing earth field can not occur, to be arranged to thereby to prefer ground radiation over room radiation. It will also be at the same time Made the suggestion to deviate slightly from the distance, in order to avoid this especially to save on fattening costs.
Vorliegende Zusatzerfindung schlägt vor, die obere Hälfte des. Dipols in diesen Anordnungen aus parallel geschalteten Drähten aufzubauen, die in ihrem unteren Teil seitlich aus dem Mast herausgeführt und in ihrem oberen Teil durch aus dem Mast herausragende Stützen gespannt sind.The present additional invention suggests the upper half of the dipole in these arrangements build up of wires connected in parallel that are in their lower part laterally led out of the mast and through in its upper part supports protruding from the mast are stretched.
In der Abbildung ist eine derartige Antennenanordnung beispielsweise veranschaulicht. Die obere Hälfte des Dipols besteht aus,einer Vielzahl von Drähten, während die unter Hälfte aus einem einfachen Leiter besteht. In der Mitte ist eine Selbstinduktionsspule 1.1 eingebaut. Der obere Teil des Dipols besteht aus einer Mehrzahl von Drähten D", die an Stützen außerhalb des Mastes abgespannt sind.Such an antenna arrangement is shown, for example illustrated. The upper half of the dipole consists of, a multitude of wires, while the lower half consists of a simple ladder. In the middle is one Self-induction coil 1.1 built in. The upper part of the dipole consists of one A plurality of wires D ″, which are guyed to supports outside the mast.
Der Vorteil der Anordnung besteht darin, daß eine allzu große Nähe des. Mastes an den. spannungsführenden Teilen vermieden wird. was zu Cberschlägen führt, da am Dipolende bekanntlich die größte Spannung herrscht. Die seitliche Durchführung der Dipoldrähte gelingt leichter unter Einschaltung größerer Abstände .als die Befestigung eines einzigen Dipoldrahtes bis zur Mastspitze. Ein weiterer Vorteil ist darin zu sehen, daß durch die Anordnung außen am Mast das Diagramm durch den Mast selbst nicht verzerrt «-ird, wie dies beispielsweise bei einem Dipol, der innerhalb des Mastes aufgehängt ist, leicht der Fall sein kann.The advantage of the arrangement is that it is too close of the. Mast to the. Live parts are avoided. what to overturns leads, since the dipole end is known to have the greatest voltage. The lateral implementation the dipole wires succeed more easily with the inclusion of larger distances than the attachment a single dipole wire to the top of the mast. Another benefit is in it too see that the arrangement on the outside of the mast means that the diagram through the mast itself is not distorted, as is the case, for example, with a dipole that is within the The mast is suspended, can easily be the case.
