ANTENNA ANGLE
When using the AccuNav Sport™, try to make certain
the antenna is parallel with the ground, or nearly so as
shown at right. Since the signals from the satellites are
"line of sight", a flat antenna gives you a better chance
of being able to receive the signals from all of the
available satellites.
Also, trees, buildings, carports (even your body), can
block the signals from the satellites. When using this
unit in heavy brush or timber, remember that it may lose
track on one or all of the satellites until you move into a
clearing.
We have successfully used the AccuNav Sport™ in
cars and trucks since the satellite's signal passes through
glass. However, antenna placement can make a differ-
ence in receiving the signals or not.
