Installation

This will provide a more stable position fix, and also offers redundancy if one
of the satellite systems goes offline. If you install it near a window, under a
fiberglass deck or inside a centre console, you will not require an external
GPS antenna. If your installation location is deep inside your boat where the
GPS antenna will not be able to receive satellite signals you will need an
external GPS antenna. We recommend the em-trak GPS100, which is
available for purchase from www.em-trak.com
Please note the following guidelines when installing an external GPS
antenna.
● You will require a 1" (inch) 14 TPI threaded if you choose to pole
mount the GPS antenna.
● Mounting the external GPS antenna at a low point on the boat will
minimise the effect of pitch and roll on your position.
● Do not mount your antenna in the direct path of a radar or any other
transmitting equipment.
