TIP | Run the antenna cables through the boom sections while
assembling the boom. Be careful not to pinch or damage the
cables.
Attached to one end of the boom unit is a cable guide that reduces the
stress on the antenna feed cable; this cable guide must be removed to
install the boom.

Remove the bolts that hold the cable guide in place, and set the unit to
the side.

Slide the end of the boom where the cable guide was attached through
the receptacle hole on the carrier so that the cable guide will be on the
same side of the tower as the motor base.
 When the center block reaches the carrier, tighten the hand knobs to
secure the boom in place.
 Reinstall the cable guide.
