Abstract
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.
