MONITORING SYSTEM IN TRANSMITTING ANTENNAS

A device for monitoring the health of a transmission line that connect a signal source (20, 31) to an antenna (5, 6, 7, 8, 32), the device including one coupler or a plurality of couplers (C1, C2, C3, 35), at determined distances along the transmission line (36), and a processing unit (22) sensitive...

Beschreibung
Zusammenfassung:	A device for monitoring the health of a transmission line that connect a signal source (20, 31) to an antenna (5, 6, 7, 8, 32), the device including one coupler or a plurality of couplers (C1, C2, C3, 35), at determined distances along the transmission line (36), and a processing unit (22) sensitive to the signals present at least one port of each of the couplers, and arranged to compute the phase shift (α) between the direct and reflected component at a predetermined position of the transmission line, and/or an electrical length of the transmission line, and/or a delay of the transmission line,based on the measured signals.
