2.5 VHF Antenna
Note North American Users - To meet FCC (Federal Communications
Commission) rules on Radio Frequency Exposure, it is recommended
that the VHF antenna is mounted at least 3m (10ft) away from any area
accessible to any personnel on board. If this distance is achieved by
vertical separation, the antenna must be at least 5m (16.5ft) above deck.
This guideline applies only to antennas not exceeding 3dBi gain.
WARNING
Failure to observe these recommendations may expose
those within the MPE (Maximum Permitted Exposure)
radius of 3m (10ft) to RF absorption levels that exceed
the FCC safe limits.
The most important factor in the performance of any AIS transceiver will
be the quality and positioning of the antenna.
