Abstract

A magnetic resonance apparatus has magnet systems which respectively generate a basic magnetic field, gradient magnetic fields and a high-frequency magnetic field. A start element is connected to an end element via a coaxial cable. The coaxial cable is divided into at least two cable sections that are coupled to one another via a transformer having transformer coils. The transformer coils are directly connected to inner conductors of the respective coaxial cable sections and are connected to outer conductors of the respective coaxial cable sections via tuning capacitors.
