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.
