Installation
If a problem is found, try altering the location of the unit
or wiring. Often moving the antenna a few feet away from the
source of interference will solve the problem. When a suitable
configuration is found, a permanent installation should be
made. Select the mounting location according to your prefer-
ences. Keep in mind that from this mounting location cables
will be routed to the NMEA listening device.
Mounting the GPS 17 with cable outside mount:
1. Place the cable in the vertical slot along the side of the
base of the unit.
2. Screw the GPS 17 onto the mount. Make sure that you
do not overtighten the head. It is possible to tighten the
unit to the point that the cable may be cut in two.
3. With the GPS 17 and mount installed, fill the remaining
gap in the cable exit on the with a marine sealant.
4. Route the power/data cable from the GPS 17 to the
desired device. Excess cable may be shortened or coiled
together and secured in an inconspicuous location.
Three common sources of interference for GPS units are:
Radar
ABOVE- OK
BELOW- OK
EMI
SS JAYHAWK
3'
VHF Radio Antenna
Radar
EMI (Electromagnetic Interference) from engine components
When routing the power/data
cable, try to avoid:
• Sharp edges which may cut
the cable.
• Routing the cable parallel to
other power lines.
• Excessively twisting, straining
or bending the cable.
