Abstract
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 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.
