Garmin GPSMAP 130 - Manual (Page 77)

Installing the GPSMAP 130
The GPSMAP 130 must be properly installed according to the following instruc-
tions to get the best possible performance. The GPS antenna should be installed
first, followed by the display unit. To complete the installation, you’ll need the
appropriate fasteners for your installation, and a 1” x 14-thread marine antenna
mount available at most marine dealers.
Mounting the GPS antenna
The antenna should be mounted in a location that has a clear, unobstructed
view of the sky in all directions to ensure the best reception. Avoid mounting the
antenna where it will be shaded by the boat’s superstructure, a radome antenna, or
mast. Sailboat users should avoid mounting the antenna high on the mast to pre-
vent inaccurate speed readings caused by excessive heeling. Most marine VHF and
loran antennas will not seriously degrade the GPS antenna’s reception. Never paint
the antenna or clean it with harsh solvents.
The GARMIN antenna screws directly onto any standard 1” x 14-thread antenna
mount. If you need to raise the antenna to avoid shading, try using a 1” x 14-
thread extension mast available at most marine dealers.
To install the GPS antenna:
1. Screw the antenna directly onto the 1” x 14-thread mount.
2. Route the cable to the mounting location of the display unit. Use the appropriate tie-
wraps, escutcheon plates and sealant to secure the cable along the route and through
any bulkhead or deck.
3. Once the GPSMAP unit has been installed, connect the cable to the antenna connector
on the back of the display unit. Make sure that you turn the antenna cable connector 1/4
turn clockwise to lock the cable into place.
