signals. The antenna/receiver module comes with a 25-foot Y-adapter
extension cable. This module can be mounted on a flat surface or pole,
or an optional magnet is available for temporary mounting on any
ferrous surface.

You need to select an antenna installation location that has a clear,
unobstructed view of the sky. After the module is installed, connect it to
the unit. The LGC-2000 can communicate with your GPS unit either
directly (using the supplied extension cable) or through a NMEA 2000

network.
NOTE
See the module’s instruction sheet, publication part number 988-
0147-981, for complete installation instructions.
In an automobile, you may achieve good results by simply placing the
external antenna on the top of the dash, at the base of the windshield. A
piece of the rubber non-skid shelf liner material available in recreational
vehicle supply stores will help hold the antenna in place. This may not
work well if you have a cab-over design pickup truck camper or motor
home. If dashboard reception is poor, simply relocate the antenna module
elsewhere on the vehicle for a clearer view of the sky.
Connecting Directly to the Unit
After the module is installed, attach it to the end of the Y-adapter
extension cable as shown in the following diagram. To connect it to the
unit, insert the extension cable's splitter plug into the Network socket
on the back of the unit and your system is ready to use.
