Garmin GPS 19x NMEA 2000 Installation Instructions

GPS 19x NMEA 2000

Installation Instructions


Always wear safety goggles, ear protection, and a
dust mask when drilling, cutting, or sanding.
When drilling or cutting, always check what is on the
opposite side of the surface.
The Garmin GPS 19x NMEA 2000 high-sensitivity
GPS antenna provides position information to your
existing NMEA 2000 network.
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.
Registering the Device
• Keep the original sales receipt, or a photocopy, in
a safe place.
For future reference, write the serial number
assigned to your antenna in the space provided. It is
located on a sticker on the bottom of the antenna.

Mounting type and Location
Considerations
You can mount the antenna on a flat surface,
attach it to a standard 1 in. OD, 14 threads per in.,
pipe-threaded pole (not included), or install it under
fiberglass.
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.

Notice
.
• 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
–
• The antenna should not be mounted where it is
shaded by the superstructure of the boat
radome antenna, or the mast.
• The antenna should not be mounted near the
engine or other sources of Electromagnetic
Interference (EMI)
• If a radar is present, it is best to install the
antenna above the path of the radar
it is acceptable to install it below the path of the
radar if necessary. The antenna should not be
š
installed directly in the path of the radar
™
• 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
• 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.
testing the Mounting Location
1
Temporarily secure the antenna in the preferred
mounting location and test it for correct operation.
2
If you experience interference with other
electronics, move the antenna to a different
location, and test it again.
3
Repeat steps 1–2 until you can verify that the
antenna operates correctly.
4
Permanently mount the antenna.
Surface-Mounting the Antenna
Before you permanently mount the antenna, test the
mounting location for correct operation
Use the surface-mount bracket
template.
