1. What is AIS? AIS is the short form for Automatic Identification System. Since 01.01.2005 all SOLAS-Ships above 300 tons and all passenger vessels have to be equipped with AIS. All ships equipped with AIS permanently broadcast via two dedicated VHF channels (CH 87B and 88B) information about their MMSI-number (MMSI: The vessel’s Maritime Mobile Service Identity number), call sign, name, position, course, heading, speed, rate of turn and type of vessel.

4. Installing an AIS VHF Antenna The VHF antenna is not included in the AIS-700 package because the installation of antenna is different from one vessel to another. You can find an antenna from a marine electronics outlet. The AIS VHF antenna should be placed in an elevated position that is as free as possible with minimum of 0.5 meters in the horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large vertical obstruction.
Please refer to the below two pictures for the suggested installation of VHF antenna. Horizontal separation Distance Vertical separation Distance www.sanav.com San Jose Technology, Inc. ｜11F., No.2, Sec. 114, Jhongyang Rd., Tucheng City, Taipei County 236, Taiwan (R.O.C.) ｜Tel: 886-2-22694456｜Fax: 886-2-22694451｜sanav@sanav.
Here are some suggestions before you buy an antenna and installation. 1. Antenna Type: VHF antenna 2. Connector type: BNC plug, 50 ohms. 3. Separate the AIS VHF antenna as far as possible from the other VHF antenna. 4. The AIS VHF antenna should be at least 3 meters away from the high power transmitters. 5. The antenna should be able to see the clear sky and avoid the large obstructions. 6. The higher the antenna is mounted, the longer the range is. www.sanav.com San Jose Technology, Inc. ｜11F., No.2, Sec.
