A remote feeder reactance coil and a signal transmission system. The invention relates to a remote feeder reactance coil (100) for energy input and output in signal transmission lines, as well as in signal transmission systems including signal transmission lines, where intermediate amplifiers are supplied with electrical energy via said signal transmission lines. In order to provide a reactionless connection of a high-frequency signal path and a low-frequency energy supply in signal transmission systems over an as large as possible frequency range, at the same time keeping the required manufacturing effort small, the invention provides a remote feeder reactance coil (100) including a primary winding (102) carrying a feed current as well as an attenuation circuit (118) in which at least the secondary winding (112), which is part of said attenuation circuit (118), or the primary winding (102) are of an electrically insulated conductive material, wherein said secondary winding (112) and said primary winding (102) interact through capacitive and/or inductive coupling.

L'invention concerne une bobine de réactance (100) d'une ligne de transmission à distance pour assurer l'entrée et la sortie d'énergie dans des lignes de transmission de signaux, ainsi que dans des systèmes de transmission de signaux comprenant des lignes de transmission de signaux dans lesquels les amplificateurs intermédiaires sont alimentés en énergie électrique via lesdites lignes de transmission de signaux. La présente invention vise à assurer une connexion sans réaction d'une trajectoire de signaux haute fréquence et d'une alimentation en énergie basse fréquence dans les systèmes de transmission de signaux, sur des plages de fréquence les plus grandes possibles, tout en réduisant les problèmes de fabrication. Dans ce but, la présente invention traite d'une bobine de réactance (100) d'une ligne de transmission à distance comprenant un enroulement primaire (102) transportant un courant d'alimentation ainsi qu'un circuit d'atténuation (118) dans lequel au moins l'enroulement secondaire (112) qui fait partie dudit circuit d'atténuation (118) ou l'enroulement primaire (102) sont constitués d'un matériau conducteur électriquement isolé. Ledit enroulement secondaire (112) et ledit enroulement primaire (102) coopèrent par couplage capacitif et/ou inductif.
