If the antenna is mounted facing the front of the vehicle, remove the driver side cover on the elevation
axis pivot shaft to gain access to the inclinometer. The inclinometer is covered with an aluminum cover
to protect it from weather and mechanical damage.
One mounting screw hole is slotted. The inclinometer is mechanically set at the correct boresight
position of 12.8° for the 1.2m, 15.8° for the 1.5m and 18.8° for the 1.8m antenna when the reflector face
surface is perpendicular to gravity. This is accomplished by loosening the allen screw (9/64 allen
wrench) and rotating the inclinometer. The inclinometer may also be electrically zeroed using the
controller. See section 4.1.1 of the Controller manual.
