1. INSTALLATION
1-11
• The thickness of the antenna unit platform must be over 15 mm.
• The reinforcement rib must be installed diagonally as shown below.
2. Referring to the outline drawing, drill eight mounting holes (

16 mm) in the mount-
ing platform.
3. If two insulation sheets (type: 03-183-3106)
are supplied in the installation materials, place
these sheets as aligned with eight mounting
holes. If the insulation sheets are not supplied,
go to next step because the sheets have been
attached on the antenna unit already.
4. Place the Antenna Unit on the mounting platform, then orient the unit so the bow
mark on its base is facing the ship’s bow.
Note: When the Antenna Unit is placed on the platform, make sure that the plat-
form is not inclined.
5. Fasten the Antenna Unit to the mounting platform with M12

70 hex bolts, nuts, flat
washers and seal washers (supplied). The torque must be 49 N•m. Fasten the
double nuts, referring to the installation guide (C3900Y01) at the back of this man-
ual.
Note: The bolts can also be inserted from the underside of the platform.
