A magnetic resonance scanner includes an antenna system, such as a body coil, mechanically coupled to a support structure, such as a gradient coil, via a suspension system. The suspension system has a setting mechanism in order to reversibly set a coupling parameter value of the mechanical coupling between the antenna system and the support structure and/or a position or location of the antenna system relative to the support structure. The coupling parameter may be set during operation of a magnetic resonance imaging system including the magnetic resonance scanner.
