Abstract: A local coil includes a transmitter, to which magnetic resonance signals are supplied and which modulates a carrier signal oscillating at a carrier frequency using the magnetic resonance signals. The local coil includes a transmitting antenna, to which the modulated carrier signal is supplied and which sends the modulated carrier signal in a beam to a control and evaluation device of a magnetic resonance system. The beam has a mean direction of radiation. In a vertical plane containing the mean direction of radiation, the beam covers a vertical angle, and in a transverse plane containing the mean direction of radiation and running orthogonally to the vertical plane, the beam covers a transverse angle. The local coil includes an adjusting device that adjusts the mean direction of radiation independently of the orientation of the local coil relative to the vertical.
