5 Installation
5.1 Positioning
When installing Poseidon into a vehicle, correct positioning is essential to achieve good
performance. There are a number of goals in selecting a mounting site in your application, these
are:
1. Poseidon should be mounted in a position that allows it to have a clear and unobstructed
view of the sky.
2. Poseidon should be mounted in a position that is above the water line when the vehicle is
surfaced.
3. The coaxial cable should be routed away from high voltage and high current wiring as well
as rotating and reciprocating machinery.
4. The coaxial cable should not be pinched or squashed, and care should be taken if cable
ties or other fastening methods are used to secure the cable.
5. The coaxial cable should not be bent beyond its minimum bend radius.
5.2 Mounting
Four M4 5 mm deep threaded mounting holes are available on the base of the unit. It is
recommended that all four holes are used for secure mounting of the antenna. Screws made from
316 stainless steel should be used to avoid any problems with corrosion.
If mounted to dissimilar metals where galvanic corrosion may occur it is recommended that a
rubber or plastic isolation pad is used between the antenna and other metal and either nylon
screws or alternatively stainless steel screws with isolation washers are used.
