Garmin 210 - Manual (Page 73)

To begin installation, you’ll need to select a suitable mounting position for
the antenna and the GPSMAP unit. Once you’ve identified the best mounting
locations for your application, install the antenna and cable first, then the unit
and wiring harness.
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 in all conditions.
Avoid mounting the antenna where it will be shaded by the boat’s superstruc­
ture, a radome antenna, or mast. Most marine VHP 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"x14thread mount.
2. Route the cable to the mounting location of the display unit, using the appropri­
ate 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
1/4 turn clockwise to lock the cable into place.
CAUTION!
Never cut or modify the antenna cable. If the
standard cable is not long enough for your
application, see your dealer for the proper
GARMIN cable extension.
