5.3.2 AIS Display flush mount assembly NOTE: The Pilot Plug is intended to be connected to the Display, although an alternative connection is available on the transponder. The cabling arrangements should take this into consideration when flush mounting the Display. A cutting template is supplied with the flush mounting kit. This template carries full fitting instructions.
5.4 Antenna units The AIS Transponder has to be connected to two antennas: a VHF antenna and a GNSS antenna. The GNSS (GPS) antenna is supplied as standard. 5.4.1 Antenna mounting position In accordance with IMO guidelines, antennas should be mounted in positions which, as far as possible, minimise interaction between them.
2. The GNSS antenna must have a free view through 360 degrees with a vertical angle of 5 to 90 degrees above the horizon. 3. As the received GNSS signal is very sensitive to noise and interference generated by other onboard transmitters, ensure that the GNSS antenna is placed as far away as possible from Radar, Inmarsat and Iridium transmitters. Ensure the GNSS antenna is free from direct view of the Radar and the Inmarsat beam.

6 Electrical connections This installation guide takes into account the IMO “Guidelines for installation of Shipborne Automatic Identification System”. However both the IMO publication and these instructions must be taken as guidance only; individual circumstances must take precedence. This guide is concerned only with the installation of the AIS transponder unit and does not cover the installation of any peripheral equipment connected to the transponder.
6.3 VHF and GNSS (GPS) antenna cable connections The VHF and the GNSS antenna cables are connected directly to the transponder through a UHF and a TNC plug respectively. The coax cable plugs must be attached directly to the cables; the outer insulation must not be connected in the cable cleat but in the coax plug as illustrated below.
6.3.1 VHF antenna To make sure that the transmitted and received VHF signal is not interfering with Radar signals, other VHF transmission or power lines it is important that the connection between the VHF antenna and the transponder is of a high quality double shielded coax cable. It is recommended to use a RG214 cable and PL259 connector.
6.4 Connection terminals The AIS Transponder has detachable terminal blocks for connection of cables. Dedicated connections are provided for power sources, sensors, the Display and other interfaces. Refer to the wiring diagram, attached as an appendix, for details of connections to the terminal blocks. 6.4.1 Fuse values The main system fuse (3.15 Amp) is located beside the connectors on the transponder chassis. Fuse description Main system fuse Fuse value 3.15 Amp Part No. 99-084 6.4.
