Notice
When drilling or cutting, always check what is on the
opposite side of the surface.

The antenna must be properly installed according
to these instructions. You need the appropriate
fasteners, tools, and mounts listed in each section.
These items are available at most marine dealers.

You can mount the antenna on a at surface,
attach it to a standard 1 in. OD, 14 threads per in.,
pipe-threaded pole (not included), or install it under
berglass.
For optimal performance, consider these guidelines
when selecting the antenna mounting location.
• The antenna must be mounted 5.9 in. (150 mm)
from a compass to avoid interference.
• To ensure the best reception, the antenna
should be mounted in a location that has a clear,
unobstructed view of the sky in all directions ➊.
➊ ➌➋
• The antenna should not be mounted where it is
shaded by the superstructure of the boat ➋, a
radome antenna, or the mast.
• The antenna should not be mounted near the
engine or other sources of Electromagnetic
Interference (EMI) ➌.
• If a radar is present, it is best to install the
antenna above the path of the radar ➍, though
it is acceptable to install it below the path of the
radar ➎ if necessary. The antenna should not be
installed directly in the path of the radar ➏.
➏
➎
➍
• The antenna should be mounted at least 3 ft.
(1 m) away from (preferably above) the path of a
radar beam or a VHF radio antenna ➐.
➐
• On a sailboat, to prevent inaccurate speed
readings caused by excessive heeling, the
antenna should not be mounted high on the
mast.
• The antenna provides more-stable readings
when located nearer to water level.

The speed lter setting on the antenna can help
reduce unnecessary drift-alarm triggers as well as
potentially sporadic position information. The speed
lter averages the data provided by the antenna to
provide smoother position data updates. The speed

situations.

However, there is no guarantee that interference will
not occur in a particular installation. If this equipment
does cause harmful interference to radio or television
reception, which can be determined by turning the
equipment off and on, the user is encouraged to try
to correct the interference by one of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
