Description

Band für Rahmenantennen. Es ist an sich bekannt, Rahmenantennen für die Zwecke der drahtlosen Telegraphie aus endlosen Bändern herzustellen. Man schneidet ein Stück des Bandes, dessen Länge und Umfang@ der gewünschten Rahmenantenne gleich ist, vom Band ab und verbindet die freien Enden zu einer Spule. Der so erhaltene Bandring wird dauernd oder jedesmal beim Gebrauch auf einem Träger befestigt.Tape for loop antennas. It is known per se, loop antennas for to create the purposes of wireless telegraphy from endless ribbons. One cuts a piece of tape the length and circumference of which @ the desired loop antenna is the same is, from the tape and connects the free ends to a coil. The thus obtained Band ring is attached to a support permanently or each time it is used.

Gegenstand der Erfindung ist die Herstellung eines solchen Bandes aus isolierten Drähten ohne Verwendung eines besonderen isolierenden Bandes oder zwis^hengewebter Textilfäden als Unterlage. Man benutzt dazu zweckmäßig Litzendrähte wegen ihrer Biegsamkeit. Die einzelnen Drähte werden nach Art eines flachen Zopfes untereinander zu einem endlosen Band verflochten. Um die einzelnen Drähte unterscheiden zu können, werden sie in bekannter Weise verschieden gefärbt oder sonst irgendwie gekennzeichnet.The invention relates to the production of such a tape from insulated wires without the use of a special insulating tape or Interwoven textile threads as a base. It is advisable to use stranded wire for this purpose because of their flexibility. The individual wires are made in the manner of a flat braid interwoven in an endless ribbon. To distinguish the individual wires to be able to, they are colored differently in a known way or in some other way marked.

Zur Verminderung der Innenkapazität ist es zweckmäßig, nicht jeden Leiter über die ganze Breite des Bandes laufen zu lassen, sondern nur in der Breite von 3 bis S Einzelabständen hin und her zu führen. Dadurch wird auch die Unterscheidung der Einzeldrähte erleichtert.To reduce the internal capacity, it is useful, not everyone Let the ladder run across the entire width of the tape, but only across the width to lead back and forth from 3 to S individual distances. This also makes the distinction the single wires made easier.
