Items such as electrical motors, generators, alternators, strobe lights, radio transmitters,
cellular phones, microwave dishes, radar, active antennas, etc., all generate electrical and
magnetic fields which can interfere with the GPS or WAAS signal. Mount the antenna away from
such potential sources of interference.
The GPS can be de-tuned by close proximity to other objects. For example, if you place the
antenna under fiberglass its performance could be degraded. Usually, if you lower the
antenna so that at least a quarter of an inch gap is made between the antenna and the covering
plastic or fiberglass, acceptable performance can be achieved. Metal or other dense materials
will completely block the GPS signals.
ANTENNA CABLE
The antenna cable should be routed around your machine so that it’s out of the way. Make sure
it is not subject to scraping or excessively sharp bending. Also, make sure the antenna cable
has some slack. It needs just enough to prevent strain on the connections.
It’s important that the cable’s outer insulation jacket is never broken. Make sure that the
cable is routed away from sharp or abrasive surfaces. Also, make sure the metal surfaces of
the connectors on the cable do not come in contact with the chassis of your machine.
