Die Neuerung betrifft eine collineare (vertikal gestockte) Mobil-^ funkantenne im wesentlichen für das Oj7m und 0j23m Band.- Auch fUr andere Bänder, sowie als 5/8 Lambda Strahler ist diese Konstruktion verwendbar.The innovation concerns a collinear (vertically stacked) mobile radio antenna, mainly for the 0j7m and 0j23m bands. This design can also be used for other bands, as well as as a 5/8 lambda radiator.
1. offenen, sichtbaren Phasendrehspulen.1. open, visible phase shift coils.
2. ummantelten oder umspritzten Phasendrehspulen die sich als Strahlerverdickung hervorheben.2. coated or molded phase shift coils which stand out as radiator thickening.
In der neuen Bauform wird der äußere Durchmesser der Phasendrehspule dem der Strahlerelemente gleichgesetzt. Dadurch hebt sich die Phasendrehspule nicht oder nur unwesentlich vom übrigen Teil des Strahlers ab. Es entstehen dadurch wesentliche Vorteile im Gebrauch:In the new design, the outer diameter of the phase shift coil is equal to that of the radiator elements. As a result, the phase shift coil does not stand out, or only slightly, from the rest of the radiator. This results in significant advantages in use:
1. es entstehen keine Windgeräusche durch offenliegende Phasendrehspulen. 1. There is no wind noise due to exposed phase shift coils.
2. kein hängenbleiben an Hindernissen (Büsche,Äste) durch einhakende Spulen oder Strahlerverdickungen2. No getting caught on obstacles (bushes, branches) due to hooked coils or radiator thickenings
3» einfache Reinigung durch homogenen Aufbau3» easy cleaning due to homogeneous structure
4. bessere elektrische Eigenschaften (größerer Antennengewinn)4. better electrical properties (greater antenna gain)
5. Korrosionsschutz durch Kunststoffüberzug.5. Corrosion protection through plastic coating.

Der Antennenstrahler besteht aus einem elektrisch leitenden Rohrelement (z.B. Messing), je nach Bauart in 1/4 Lambda Lange oder 3/4 Lambda Länge (Teil 1). In dieses Rohr wird ein Kunststoffstab (z.B. GFK) eingeschoben (Teil 2). Die Phasendrehspule (Teil 3) wird über den Kunststoffstab (Teil 2) geschoben und mit dem unteren Rohrelement (Teil 1) elektrisch leitend verbunden. Oberhalb der Phasendrehspule (Teil 3) wird ein Metallgeflecht (Teil 4) mit 1/2 Lambda oder 5/8 Lambda Länge aufgeschoben und mit dem oberen Ende der Phasendrehspule (Teil 3) elektrisch leitend verbunden.Der Antennenstrahler wird mit einem Schrumpfschlauch oder Flüssigkunststoff (Teil 5) ummantelt.The antenna radiator consists of an electrically conductive tube element (e.g. brass), depending on the design, 1/4 lambda long or 3/4 lambda long (part 1). A plastic rod (e.g. GRP) is inserted into this tube (part 2). The phase shift coil (part 3) is pushed over the plastic rod (part 2) and electrically connected to the lower tube element (part 1). A metal mesh (part 4) with a 1/2 lambda or 5/8 lambda length is pushed over the phase shift coil (part 3) and electrically connected to the upper end of the phase shift coil (part 3). The antenna radiator is covered with a shrink tube or liquid plastic (part 5).
Die Neuerung ist in einer Reihe von Ausführungen möglich. Die Strahlerteile und Phasendrehspulen sind vom Durchmesser so aufeinander abgestimmt* daß im Gegensatz zu bekannten Konstruktionen die Phasendrehspule nicht als wesentliches Teil des Antennenstrahlers sichtbar auftritt. Es kann somit, ein für collineare Antennen neuartiges und völlig homogenes Erscheinungsbild erreicht werden. Ein Aufbau des Antennenstrahlers ist wie folgt möglich:The innovation is possible in a number of designs. The radiator parts and phase shift coils are matched to each other in terms of diameter* so that, in contrast to known designs, the phase shift coil is not visible as an essential part of the antenna radiator. This makes it possible to achieve a completely homogeneous appearance that is new for collinear antennas. The antenna radiator can be constructed as follows:
1/4 Lambda- Phasendrehspule- 1/2 Lambda1/4 Lambda- Phase shift coil- 1/2 Lambda
1/4 Lambda- Phasendrehspule- 5/8 Lambda1/4 Lambda- Phase shift coil- 5/8 Lambda
