2.5 GPS Antenna Installation
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 8 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.
CAMINO-108S is tested with the GPS antenna GA-22. It’s recommended to use GA-22 to
ensure optimal reliability of your AIS system.
Pole Mounting:
For pole mounting the GA-22, a 1 inch 14 TPI thread pole will be required.
1. Align the GPS cable with the opening slot found on the side of the GPS Antenna.
Note: Lightly pull the GPS cable outward to ensure that the cable is not lodged between
the GPS Antenna and the pole while is being secured.
2. Align the GPS Antenna to the pole and turn clockwise until is securely tightened.
