Description

Gegenstand des Patents 9r6 834 ist eine UKW-Antenne, die zum Empfang von längeren, - senkrecht polarisierten Wellen (z. B. Rundfunkbereiche Kurz-Mittel-Lang) mitbenutzt wird und bei der ein Teil der symmetrischen Doppelleitung zum Empfänger zur Vergrößerung der effektiven. Antennenhöhe bei Langwellen als tragender Doppelmastausgebildet ist, wobei der gegenseitige Abstand der beiden Masten so gewählt ist, daß der Wellenwiderstand der Zuleitung erhalten bleibt.The subject of patent 9r6 834 is a VHF antenna that is used for reception of longer, - vertically polarized waves (e.g. broadcasting areas short-medium-long) is also used and in which part of the symmetrical double line to the receiver to increase the effective. Antenna height for long waves designed as a supporting double mast is, the mutual distance between the two masts is chosen so that the wave resistance the supply line is retained.

Um die UKW-Empfangsenergie zu erhöhen, werden vielfach zwei oder mehr UKW-Antennen übereinander angeordnet und durch Doppelleitungen miteinander verbunden.To increase the FM reception power, two or more are often required VHF antennas arranged one above the other and connected to one another by double cables.

Als Weiterbildung des Gegenstandes des Hauptpatents werden, gemäß der Erfindung diese-#erbindungsleitungen in der gleichen Weise wie die Zuleitungen nach dem Hauptpatent als wie,-die Masten ausgebildet.As a further development of the subject matter of the main patent, according to According to the invention, these connecting lines are used in the same way as the supply lines according to the main patent as how, -the masts are designed.

Ein Ausführungsbeispiel der erfindungsgemäßen Anordnung zeigt die Abbildung. Die beiden UKW-Ringantennen i und 2 sind übereinander angeordnet. Die untere ist mit Hilfe eines Isolierteils 3 auf dem geerdeten Mast 4 befestigt. Die Doppelleitung, welche die beiden Antennen miteinander verbindet, ist als Doppelmast ausgebildet, der aus den beiden Rohren 5' und 6 besteht, die im Isolierteil 3 befestigt und durch das Isolierteil 7 an ihrem oberen Ende zusammengehalten werden. Die UKW-Antenne 2 ist ebenfalls am Isolierteil 7 befestigt. Um die effektive Antennenhöhe für- die längeren. Wellen noch weiter zu erhöhen, ist auf das Mastrohr 5 ein weiteres Rohr 8 aufgesetzt. Man kann auch die beiden Rohre 5 und 6 über das Isolierstück 7 hinaus um ein Viertel der UKW-Betriebswellenlänge verlängern und ihre Enden durch eine Kurzschlußbrücke miteinander verbinden, oder die Zusatzrohre ohne Kurzschlußbrücke eine halbe Wellenlänge lang machen.An embodiment of the arrangement according to the invention shows Illustration. The two VHF ring antennas i and 2 are arranged one above the other. the The lower one is attached to the grounded mast 4 with the aid of an insulating part 3. the The double line that connects the two antennas is a double mast formed, which consists of the two tubes 5 'and 6, which are fastened in the insulating part 3 and are held together by the insulating part 7 at their upper end. The VHF antenna 2 is also attached to the insulating part 7. To determine the effective antenna height for the longer. To increase waves even further, another tube is on the mast tube 5 8 put on. You can also use the two tubes 5 and 6 beyond the insulating piece 7 extend by a quarter of the VHF operating wavelength and extend its ends by a Connect the short-circuit bridge with one another, or the additional pipes without a short-circuit bridge make it half a wavelength long.
