F\u00fcr den Frequenzbereich \u00fcber 1 GHz spezifiziert CISPR 16 die Verwendung von Breitband-Hornantennen f\u00fcr gestrahlte Ger\u00e4uschmessungen. Standard-Breitband-Hornantennen f\u00fcr EMV-Anwendungen sind recht kostspielig und decken einen Frequenzbereich ab, der weit gr\u00f6\u00dfer ist als der von typischen preiswerten EMV-Pre-Compliance-Spektrum-Analysatoren. Um eine f\u00fcr EMV-Pre-Compliance-Messungen oberhalb von 1 GHz optimierte Antenne anbieten zu k\u00f6nnen, hat Tekbox die TBMA4 Doppel-Horn-Messantenne entwickelt, die mit ihrem moderaten Preis ein erschwingliches Produkt f\u00fcr EMV-Pre-Compliance-Messungen und die Erzeugung definierter Feldst\u00e4rken darstellt. Die TBMA4 ist von 1 GHz bis 8 GHz charakterisiert und hat eine f\u00fcr Doppelsteg-Hornantennen typische Richtcharakteristik. Die TBMA4 ist eine kleine Doppelsteg-Hornantenne, deren Strahlerelement aus kantenplattiertem PCB-Substrat besteht. Das Geh\u00e4use ist aus rostfreiem Stahl gefertigt. Sie ist mit einem Standard-N-Buchsenanschluss ausgestattet und wird zusammen mit einem &quot;Pistolengriff&quot;-Stativ geliefert. Ein standardm\u00e4\u00dfiges \u00bc&quot;-Gewinde an der Unterseite der Antenne erm\u00f6glicht den einfachen Anschluss an die meisten Standardstative. Optional kann die Antenne mit einer indizierten Montageplatte auf der R\u00fcckseite ausgestattet werden. Dieses Zubeh\u00f6rteil hat eine 6-mm-Gewindebohrung in der Mitte und radial angeordnete 4-mm-Gewindebohrungen in 45\u00b0-Schritten, die f\u00fcr die meisten Hornantennen typisch sind.SPEZIFIKATIONEN Typ: DoppelsteghornFrequenzbereich: 1 GHz &#8211;
