Ce vendredi 16 septembre, André F6AIX a proposé une soirée à thème très intéressante et consacrée à l’adaptation de la ligne de transmission à l’antenne. Une douzaine d’OM ont suivis les explications très accessibles. Des démonstrations des adaptations ont été réalisés directement à l’aide d’un MiniVNA : Stub, Adaptation de Braham, et Balun 1:4.
Vous pouvez télécharger la présentation complète d’André (F6AIX). En fin vous y trouverez des références et liens pertinents qui vous permettront de creuser certains des sujets.
Merci également à Jean-Louis F5OCL qui a vous conseille le visionnage de cette trouvaille, une vidéo qui répond à la question “Qu’est ce que l’impédance des câbles ?”.
