Abstract (en)
[origin: US4811032A] In a method for monitoring and controlling an antenna selector in which a large number of switching points (U11, . . . Umn) are provided in matrix arrangement in order to connect m transmitters (S1, . . . , Sm) to n antennas (A1, . . . , An) in arbitrary manner, the switching state of the individual switching points is monitored and controlled by the switching points (U11, . . . , Umn) being sequentially selected by selection of the associated rows and columns. Compared with the prior art in which separate signal lines were provided for each breaker at each switching point, this results in a distinct simplification in the wiring of the system.
