Placement of Antennas

Placement of Combination and Internal Antennas

When dealing with combination antennas, it is more important to considered GPS

performance over Comm performance. GPS signal strengths are much lower than those

typically seen by cellular networks supported by the LMU. In order to maximize the

performance the LMU should have a clear view of the sky as possible. When installing

the GPS antenna in a vehicle, make sure that there are as few obstructions as possible

close to the LMU that might block the view 360° to the horizon. As with stand-alone

GPS antennas, nothing should not block the combination antenna beyond 5° above the

horizon with the best location being near the center of the roof. For more covert installs,

directly under the front or rear-windshields are also acceptable.
