When T 2 is in the transmitting state, the input/output section 12 is not connected to the antenna, so it is in the open state.
The SWR becomes infinite, and the protective operation of the transmitter section can be confirmed. Further, these adjustments and checks can be easily performed by simply operating the interlocking operation selection switch without replacing the dummy load.
