ANTENNA INSTALLATION

The machine presets loaded into the SmarTrax system software are based on the location of the antenna at the
time the SmarTrax system was developed for your particular machine. If the antenna is not positioned exactly in
the position configured in the software, the system will not acquire and remain on the desired path and/or system
performance may degrade over time.

ANTENNA LEFT/RIGHT OFFSET (ANTENNA X POSITION)

The antenna left/right offset position is the distance from the antenna to the center of the machine. The antenna
left/right offset position is measured parallel to the machine's axle. Refer to Figure 1 below.
NOTE: It may be necessary to make adjustments to the left/right offset if the implement being used does not
align or track properly with the machine.

ANTENNA FORE/AFT OFFSET (ANTENNA Y POSITION)

The antenna fore/aft offset position is the distance from the GPS antenna to the rear axle of the machine. The
antenna fore/aft offset position is measured perpendicularly from the antenna to the machine's rear axle. Refer to
Figure 2 below.

ANTENNA HEIGHT (ANTENNA Z POSITION)

The antenna height value is the measurement from the ground to the base of the antenna.
