Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
146 words
A DIRECTIONAL RADIO TRANSMISSION AND COOPERATING RECEIVING SYSTEM COMPRISING A NUMBER OF HIGH-FREQUENCY TRANSMISSION CHANNELS, TO EACH OF WHICH IS ALLOCATED AN INDIVIDUAL TRANSMITTER, A COMBINING CIRCUIT ARRANGEMENT OPERATIVELY CONNECTING THE INDIVIDUAL TRANSMITTERS TO A COMMON ANTENNA FOR TRANSMISSION TOO A COMMON RECEIVING ANTENNA, A SEPARATING CIRCUIT ARRANGEMENT OPERATIVELY CONNECTING THE RECEIVING ANTENNA TO INDIVIDUAL RECEIVERS OF LIKE CONSTRUCTION, THE COMBINING CIRCUIT ARRANGEMENT HAVING DIFFERENT INPUT POINTS, EACH ALLOCATED TO A DIFFERENT ONE OF THE SEVERAL CHANNELS, WHICH POINTS CORRESPOND IN CIRCUIT POSITIONS TO A CORRESPONDING NUMBER OF OUTPUT POINTS FROM THE SEPARATING CIRCUIT, THE INPUT POINT OF EACH INDIVIDUAL CHANNEL TO THE COMBINING CIRCUIT AND ITS OUTPUT POINT FROM THE SEPARATING CIRCUIT BEING RELATIVELY SELECTED SO THAT EACH CHANNEL IS SUBJECTED TO THE SAME NUMBER OF REFLECTION POINTS BETWEEN THE TRANSMITTER AND RECEIVER AND TRANSIT TIME DIFFERENCE BETWEEN THE SIGNALS IN DIFFERENT CHANNELS ARE MINIMIZED.
