Install the GPS antenna where it has a clear view to the sky, so that it may access the
horizon freely with 360° degrees.
Figure 4 GPS Antenna Locations
It is recommended to keep the GPS antenna out of the transmitting beam of
high-power transmitters such as Inmarsat devices and radar.
When connecting the cables, take note of the following precautions.
Bending cables may cause damages to the inner wires and impair overall the
performances.
Each coaxial cable should be set up separately and can only be set up in a
single cable tube.
Insulation on connector port of the coaxial cable should be considered.
