VHF Antenna Installation
The quality and positioning of the antenna are the most important factors dictating AIS performance. It is
recommended that a VHF antenna with omni directional vertical polarization be specifically tuned for AIS
operation band. Since the range of VHF signals is largely decided by line of sight distance, the VHF antenna
should be placed as high as possible and at least 5 meters away from any constructions made of conductive
materials.
To avoid interference, the VHF antenna location should be placed accordingly as diagram below:
