Due to the separation of the modules, there was a problem in that the connection between the waterproof or power and signal lines between the separated enclosures 20 was difficult.

In addition, when the module box 22 is opened, wiring of the high frequency high output power amplifier 21 mounted on the front surface of the heat dissipation part 24 is difficult and causes leakage.
