• The diameter of the mast for fixing the Antenna Unit platform must be over 180
mm.
• The thickness of the Antenna Unit platform must be over 12 mm.
• The reinforcement rib must be installed diagonally.
2. Referring to the outline drawing at the back of this manual, drill four mounting
holes (15 mm) in the mounting platform.
3. Place the Antenna Unit on the 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.
4. Insert four sets of hex bolts (M1270)
attached the seal washers to the
