Radio transmission links between at least one transmission antenna and one reception antenna are monitored for faults. At least one radio reception device is tuned to the transmission frequency of at least one radio transmission device.

The antenna structure allows for decoupling between the transmission path and reception path. The antenna structure has two preferably perpendicular couplings with two separate ports, for example for the connection of a transmitting device and a receiving device. Furthermore, the impedances of the two couplings can advantageously be matched, independently of one another, to the transmitting device and receiving device and/or the frequency bands of the signals to be transmitted or received.

The turntable and the folding frame can be displaced stepwise to accommodate two or more layers.
