INSTALLATION PROCEDURE

1) Precautions for transporting and storing the antenna
• An scanner is a heavy load. Be very careful about handling it.
• Do not allow the scanner fall on its side while it is stored or being installed.
• Do not apply rope to the scanner in the way that squeezes or deforms the radiating section.
• When hoisting the scanner by a crane, do not hoist it by attaching a belt or a rope only to the
scanner's radiating section as shown in Fig.7.
• When lifting the S-band scanner（Fig.8）:
When lifting the scanner with the radiator by a crane, attach a rope (or belt/wire) to four
hoisting eyebolts attached to the scanner's chassis, and then lift the scanner so that a
protector attached on the radiator will be located between the rope and radiator.
Use suitable rope in length so that the distance from the crane's hook to the hoisting
eyebolts will be 2.5m or more.
Use the protector attached on the radiator in factory, an additional protector should be not
used. Because excessive protector will cause damage to the radiator's radome. After
installation of the scanner, remove the protector from the radiator.
If the lifting rope is attached to the scanner's support section located at the bottom of the
radiator, a load is imposed to the joint between the radiator and the chassis, then this will
cause damage.
On lifting the scanner, if the lifting rope (or belt/wire) is short, or a protector is not used, it
will scratch the radiator's radome.
And then, if a thick protector on the radome is used, it causes damage to the radome.
• When lifting the X-band scanner（Fig.9）:
Wrap a cloth around the scanner's support section located at the bottom of the radiator, and
then attach a belt to it to lift the scanner.
