Installation precaution for S-band scanner unit
If an S-band scanner unit is mounted near the end of a platform to provide suffi-
cient rotation clearance for the radiator, the scanner unit, because of its weight,
swings up and down by ship’s vibration and rolling, exerting excessive levels of
stress at the base of the radiator, which can damage the radiator. To prevent this,
relocate the scanner unit, or if relocation is not possible, reinforce the platform.
EXAMPLE
Mount the scanner unit
Directly on the mast or
on the platform, as near
as possible to the center
of the mast.
