1. HOW TO INSTALL THE UNIT
Procedure
1. Attach the rubber mat on the bottom of the antenna unit if the mat is supplied as the installation
material.
2. Connect the antenna cable to the coaxial plug on the bottom of the antenna unit.
3. Wrap the self-adhesive tape all around the coaxial connector for waterproofing and wrap the

mast and secure with hexagonal nut, spring washer and flat washer.
6. Secure other antenna bolts with a set of hexagonal nuts, spring washers and flat washers as

Note: To fix the antenna bolt, tighten first nut with torque 7.65 Nm and then tighten the second
nut with the same torque.
7. Connect the ground wire to the ground stud on the antenna mast.
8. Attach the radiation warning sticker (small) to the bow and stern sides of the antenna radome.
If these locations are not suitable, attach the radiation warning stciker (big) to the ship's body
