NTENNA

The GPSMAP 292/298 with external antenna must be properly 

installed according to the following instructions to get the 

best possible performance. To complete the external antenna 

installation, you need the appropriate fasteners and a 1" x 14-thread 

marine antenna mount available at most marine dealers. 
The GPSMAP 292/298 with internal antennas do not require this 

installation. To acquire satellites, install the unit with a clear view 

of the sky.

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.
