1. INSTALLATION
1-17
3. Lift while tilting the antenna unit so
that the front and rear loads of the
belt slings are even. The tilt angle
should be about 15 cm (about 15°)
on the opposite side with the cable
entrance side as the fulcrum point
(). Also, protect the parts where
the tilted antenna unit and the belt
slings come into contact (dashed
area) with cloth to prevent scratch-
es.
How to fasten the Antenna Unit to the mounting platform
Note: The antenna is made of cast aluminum, which is subject to electrolytic corrosion
if the mounting platform is steel or iron. To prevent electrolytic corrosion, use the sup-
plied seal washers and corrosion-proof rubber mat.
Fix the antenna unit to the mounting location, referring to the procedure below.
1. Referring to the antenna outline drawing, prepare a mounting platform. Drill eight
fixing holes of 15 mm in diameter in the mounting platform or the deck.
• The diameter of the mast for the mounting platform must be over 250 mm.
• The thickness of the platform must be over 15 mm.
• Install the reinforcement rib diagonally.
2. Lay the corrosion-proof rubber mat (supplied) on the mounting platform, aligning
the holes on the rubber mat with the fixing holes on the mounting platform.
3. Lay the antenna unit on the rubber mat, orienting it so the cable gland is directed
toward ship's bow.
4. Fix the antenna base to the mounting platform with four M12x70 hex bolts, nuts,
washers and seal washers (supplied). The torque must be 63.5 N•m. For fasten-
