Abstract: According to the invention, a cable harness (7) for a magnetic resonance system is provided, wherein the cable harness (7) is adapted for being connected to a feeding point of a magnetic resonance radiofrequency coil device (1) on one end and for being connected to an input-output unit (6) for connecting the magnetic resonance radiofrequency coil device (1) with a control and analysis unit of the magnetic resonance system on the other end, wherein the cable harness (7) comprises at least one transmission line (8) for connecting the feeding point with the input-output unit (6) and multiple radiofrequency chokes (10) which are arranged within the cable harness (7). In this way, a bulky resonant RF traps can be avoided while still the B1-excitation field of the MR system can be compensated for and coupling to local nearby coils can be reduced.
