Description
<Desc/Clms Page number 1>
Stabantenne mit Niederschlagschutz und freitragender Wicklung.
Gegenstand der Jrnindung ist eine Mabantenne mit ledersehlagschutz und h'eltiagender Wicklung.
Bei den bekannten Stabantennen wird der isolierte Antennendraht fest und dicht aneinander um einen Stab gewickelt, wobei die Wicklung den Niederschlägen ausgesetzt ist und durch Bildung eines Regen-oder Eisfilmes an der Wicklung der Empfang vermindert wird.
Nach vorliegender, in der Zeichnung dargestellter Erfindung sind am Antennenstab a Schirme b in entsprechenden Abständen c angebracht. Die Schirme haben den Zweck, Regen, Schnee und sonstige atmosphärische Niederschläge von der Antennendrahtwieklung d abzuhalten, somit Nässung oder Vereisung der Wicklung zu verhindern. Zufolge Niederschlagschutz kann blanker Draht für die Wicklung verwendet werden, wodurch ein besserer Empfang gegenüber isolierten Draht erzielt wird.
Der Antennendraht d ist freitragend mit distanzierten Windungen um den Antennenstab a gewickelt und bei den Durchgangsstellen e an den Schirmen b fest verbunden. Durch letztere Verbindungen werden die durch Wind erzeugten mechanischen Schwingungen in der Wicklung auf ein Minimum herabgesetzt, so dass die Eigenkapazität der Wicklung sich nicht wesentlich verändern kann.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Rod antenna with precipitation protection and self-supporting winding.
The subject of the invention is a Mab antenna with leather anti-slip protection and a h'eltiagender winding.
In the known rod antennas, the insulated antenna wire is tightly and tightly wound around a rod, the winding being exposed to precipitation and the reception being reduced by the formation of a rain or ice film on the winding.
According to the present invention shown in the drawing, screens b are attached to the antenna rod a at corresponding intervals c. The purpose of the screens is to keep rain, snow and other atmospheric precipitation away from the antenna wire, thus preventing the winding from getting wet or icing up. As a result of precipitation protection, bare wire can be used for the winding, which results in better reception compared to insulated wire.
The antenna wire d is wound around the antenna rod a in a self-supporting manner with spaced turns and is firmly connected to the screens b at the passage points e. The latter connections reduce the mechanical vibrations in the winding generated by the wind to a minimum, so that the self-capacitance of the winding cannot change significantly.
