替え方式。 In the transmitting antenna switching method in which the working and backup transmitting antennas are switched and used when the working antenna fails, there is an output combiner that combines the transmission outputs of two broadcasters, and a system that combines the transmitting outputs of two broadcasters when the working and backup antennas are normal and when the working antenna fails. a first switch that switches the output of the output combiner depending on the case; and a second switch that distributes the output of the first switch in the case of normal operation.
and a third switching device to the working and backup transmitting antennas, respectively, and in the case of the failure, the other switching output of the first switching device and the third
A transmission antenna switching system characterized in that the transmission antenna is connected to the backup transmission antenna via the other switching output of the switching device.
