Coat the exposed metal foot of the new antenna with an electrical insulating compound by carefully
inserting it in the mouth of the compound tube.
Hold the new antenna by the black plastic
sheathing and guide it through the hole in the
sensor box. Carefully seat the antenna in its
mating connector. When the antenna is correctly
seated, pulling on it will be met with light
resistance.
Carefully re-thread, screw-in and tighten the white
nylon hex bolt to secure the antenna in place.
Reinstall the sensor if necessary (if removed from
the boom or jib, an angle sensor will require re-
calibration during the installation procedure, see
the angle sensor installation section of the user
manual).
Verify that the sensor functions properly.
