摘要： PURPOSE: To reduce signal loss by facilitating the installation and relocation of an AIS transponder. CONSTITUTION: A plurality of members including a radio section and its antenna, a positioning section and its antenna, and a control section and a power supply section related to them out of members for composing the AIS transponder are incorporated into a single enclosure and are installed in the open air. A unit 40 installed in the open air is connected to an AIS display 20 of an interface means to a ship crew by a transmission line in a ship such as a cable. A signal that is transmitted by the transmission line in a ship is not the radio reception output itself of a VHF antenna, but is a signal that is subjected to processing such as amplification, thus preventing a signal loss in the transmission line in a ship from occurring easily. Since the plurality of members are incorporated into the single enclosure, installation and relocation are facilitated. The interference between antennas can also be restrained because of the use of a compound antenna.
