1.2.2 Installation location
The location and installation of different antennas on a ship is important to ensure ef-
fective communications. Incorrectly installed antennas will degrade performance of
the radio equipment and reduce the range of communications.
Select the location for the antenna considering the following points.
• VHF antennas should be placed in a position which is as elevated and free as pos-
sible, with at least 2 meters horizontal separation from constructions made by con-
ductive materials.
• Ideally there should not be more than one antenna on the same level.
• The location of mandatory VHF antennas should be given priority compared with
mobile telephone antennas. If they are located on the same level, the distance be-
tween them should be at least 5 meters.
