How to hoist the Antenna Unit
The Antenna Unit may be assembled before hoisting it to the mounting platform. Ori-
ent the FURUNO logo of the radiator to the bow side of the antenna unit. Hoist the an-
tenna unit with belt slings and shackles of hole diameter

20 mm (supplied locally with
required quantities according to hoisting).
Also, hoist the Antenna Unit slowly. Hoisting swiftly may cause a damage to the an-
tenna radiator or damage the radiator chassis.
There are two hoisting methods as follows.
 Upright Hoisting
Th antenna unit is positioned upright.
1. Pass both ends of two belt slings through four shackles. Attach the shackles to
the lifting fixtures (A, B, 4 places) of the chassis as shown in the figure below.
2. 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 10 cm on the opposite side with en-
trance 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
