3.4 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:
