Description

Verfahren zur Funkpeilung unter Benutzung einer wetterfesten Peilrahmenantenne mit Hilfsantenne Beim Peilen mit einer Rahmenantenne benutzt man in der Regel noch eine richtungsunempfindliche Hilfsantenne zur Bestimmung des Richtungssinnes der einfallenden Peilstrahlen und auch evtl. (bei entsprechender Umschaltung) zur Beseitigung von Minimumtrübungen.Method for radio direction finding using a weatherproof DF frame antenna with auxiliary antenna A loop antenna is usually still used for direction finding a non-directional auxiliary antenna to determine the direction of the incident bearing beams and possibly (with appropriate switchover) for elimination of minimum opacities.

Vorliegende Erfindung besteht nun darin, bei wetterfesten, durch eine metallische Schutzhülle geschützten Peilantennen diese Schutzhülle, da sie sich wie ein lineares Gebilde verhält, als Hilfsantenne oder als einen Teil derselben zu verwenden. Genügt schon ein Teil der Schutzhülle (z. B. nur der die Antennenwicklungen - umgebende Ring ohne den die Antennenzuleitungen umgebenden Schaft) zur Erzielung des Hilfsantenneneffektes, so kann natürlich der übrige Teil von dem zu benutzenden elektrisch getrennt werden.The present invention is now, with weatherproof, by a metallic protective cover protected DF antennas this protective cover, as they are behaves like a linear structure, as an auxiliary antenna or as a part of it to use. A part of the protective cover is sufficient (e.g. only the antenna windings - surrounding ring without the shaft surrounding the antenna leads) to achieve of the auxiliary antenna effect, the remaining part of the one to be used can of course be used electrically separated.

Ein Ausführungsbeispiel des Erfindungsgedankens ist in der Zeichnung dargestellt. Hier ist a die leitende, wetterfeste Hülle, innerhalb welcher die Wicklung der Peilantenne angebracht ist. b ist ein Isolierzwischenstück zur elektrischen Trennung der oberen Enden der Hülle a voneinander.An embodiment of the inventive concept is shown in the drawing shown. Here a is the conductive, weatherproof cover within which the winding the DF antenna is attached. b is an insulating adapter for electrical Separation of the upper ends of the sheath a from each other.

d ist der (zweckmäßigerweise metallische) Schaft, der als Träger der Peilantenne und als Nvetterfester Schutz ihrer Zuleitungen dient. Soll nur der Teil a als Hilfsantenne verwendet werden, so muß dieser vom Schaft d durch ein Isolierstück c elektrisch getrennt werden.d is the (suitably metallic) shaft that serves as the carrier of the DF antenna and serves as a weatherproof protection for your supply lines. Should only the part a are used as an auxiliary antenna, this must be passed from the shaft d through an insulating piece c are electrically isolated.
