INSTALLATION OF NAVTEX SENSOR
The NAVTEX Sensor is a rugged waterproof unit however care should
be taken to position it in a suitable location to optimise reception. If in
any doubt as to the suitability of a location to mount the sensor refer to
Appendix IV.
•
The Sensor should be mounted approximately vertical in an
elevated position where it will not be engulfed by sea water
•
Avoid close proximity to adjacent obstructions, other antenna or
superstructure by at least 0.5 metres
•
Never position the Sensor level with a Radar antenna aperture or
within 1m of a VHF or SSB transmitting antenna
•
The ‘top’ of a pushpit rail or radar arch are a favoured locations
•
If necessary, raise the NAVTEX sensor on an extension pole to
achieve a clear location
The sensor has a standard marine 1" 14 tpi threaded mount.
Note: due to the wide variety of possible mounting methods
(horizontal rail, vertical rail, deck, etc) ICS do not supply a sensor
mounting bracket as standard. A plastic 25mm rail mount is
available as an option - ICS part number 903.03.
• Other types of brackets and extension pole fittings are readily
available from most marine electronics stores
• Select a bracket type that will allow the sensor cable to pass freely
through the centre of the mounting boss or exit via a slot
Mounting the NAVTEX Sensor
•
Place the Sensor on top of the antenna mount
•
Holding the top of the Sensor, rotate the large plastic nut on the
bottom in order to engage the thread of the antenna mount
• Continue to tighten the nut until the Sensor is locked
• Note that it is possible to position the Sensor to face whichever way
the user desires
• Do not use a wrench to tighten the nut – hand-tighten only
