1.2.1 Installation precaution for S-band antenna unit
Due to the S-band radiator length, there may be excessive stress placed on the radi-
ator caused by vibrations, rolling and general ship movement. To prevent damage to
the antenna unit and radiator, do not install the antenna near the end of a platform. If
there is no other location available, reinforce the platform before installing the antenna
unit.
