CSB200 Class B AIS
bandwidth must cover the two AIS channels and the DSC
Channel.

Should be mounted with at least a two metre vertical separation
distance from any other VHF antenna used for speech or DCS
communication.
WARNINGS
VHF Antenna Connection
Connecting a badly mismatched VHF antenna, leaving the VHF antenna
port disconnected, or shorting the VHF antenna port will activate the
VSWR alarm, cause the unit to stop sending position reports or cause
damage to the transponder.
Radio Frequency Exposure
To meet the requirements for Radio Frequency Exposure it is necessary
to install the VHF antenna correctly and operate the AIS equipment
according to the instructions.
The VHF antenna must be mounted at a minimum distance (vertical
separation) of 3 metres from the head of any person standing on deck in
order to meet international safety directives on Maximum Permissible
Exposure (MPE) / Specific Absorption Rate (SAR).
Where no suitable structure exists to achieve a 3 metre vertical
separation then the antenna base must be mounted at least 1 metre
above the head of any person within range, all persons should stay
outside the 3-metre safety radius and if practical a grounded RF shield
should be interposed between people and the antenna.
Failure to adhere to these limits could expose persons within the 3 metre
radius to RF radiation in excess of the MPE / SAR limits.
