Important
NAVTEX antennas must be mounted clear of obstructions and at least 0.5
metres away from other antennas.
Where practical avoid locating the NAVTEX antenna close to MF / HF
transmitting antennas or VHF / AIS antennas.
Ensure that antennas cannot be snagged by mooring warps or running
rigging or engulfed by green water.
Antennas should always be mounted vertically.
