Orienting the Antenna
In order to locate and acquire satellites, the antenna must have a clear view
of the sky. While signals will pass through canvas and glass (not fiberglass),
satellite signals will not pass through metal or people.
The unit has a detachable, rotating quadrifilar antenna. Hold the unit in a
comfortable position and rotate the antenna until it is vertical. (In order to
operate more accurately, the antenna must be kept vertical.) If necessary,
insert the unit in the optional unit holder to keep it steady and to free your
hands.
NOTE
If your signal appears to be blocked, sometimes moving a few
feet in any direction will let you receive a signal. This is
especially true in an area of dense or overhanging vegetation
or structures.
If you are operating in an area with a sheltered view of the sky, you will
probably not be able to provide the antenna with a clear view and read the
unit’s display at the same time. Disconnect the antenna from the unit and
install the antenna cable between the quadrifilar antenna and the unit.
Attach the antenna to any flat surface with the suction cup mount (provided
with the unit). Be sure the antenna maintains a vertical position.
