Installing The Gpsmap 182/182C - Garmin 182/182C Owner's Manual

Installing the GPSMAP 182/182C

The GPSMAP 182/182C must be properly installed according to
the following instructions to get the best possible performance.
If you have the GPSMAP 182/182C with the built-in internal
bail mount antenna, you can skip this section and proceed to the
next page. For units purchased with the remote antenna, follow
the instructions below. To complete the installation, you need the
appropriate fasteners 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 is shaded by the
boat's superstructure, a radome antenna, or mast. Sailboat users
should avoid mounting the antenna high on the mast to prevent
inaccurate speed readings caused by excessive heeling. Most
marine VHF and LORAN antennas should not seriously degrade
the GPS antenna's reception. Never paint the antenna or clean it
with harsh solvents.

Suggested locations for mounting the external antenna.
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.
NOTE: It is possible to route
the coaxial cable either through,
or outside the antenna mount. It
is possible to remove the BNC
connector on the coaxial cable
and the coaxial cable shortened
to ease installation, however,
doing so voids the antenna
warranty. If the BNC connector
is removed, it must be replaced
with a new solder-on or crimp
BNC connector.
