Abstract
The invention relates to a system for the supervising of a receiving antenna, the system comprising partly a first sensor for the sensing of an incoming electrical signal from the receiving antenna to the first sensor, a signal processing circuit with an interface, the first sensor being permanently connected between the receiving antenna and receiving circuits and the sensing being carried out at any moment without changing the mutual connection configuration of the receiving antenna and the receiving circuits. The system is provided with a test transmitter connected to the receiving antenna via a coupling circuit and in front of a second sensor, which is permanently connected between the receiving antenna and the receiving circuits, the second sensor being arranged for the sensing of an outgoing electrical signal to the receiving antenna and the signal processing circuit being arranged to deliver, via the interface, an indication of the operability of the receiving antenna based on the sensing.
