In an antenna selector switch and a switching method, a number of antenna
units of a magnetic resonance apparatus can be operated via one RF
channel. The antenna selector switch has at least two antenna connectors
for connection with one antenna unit. A first of the antenna units can be
set in terms of its resonance frequency via a control signal. The
selector switch also has an RF channel connector for making a connection
with a radio frequency unit of the magnetic resonance apparatus; and a
switching unit to make a radio frequency connection between one of the
antenna connectors and the RF channel connector. The switching unit can
activated with the control signal. This allows a reduction of the
necessary reception channels without additional control signal lines.
