tem on the mounting platform. The location must be within 340 mm of the ground

terminal on the antenna unit. Connect the ground wire (RW-4747, 340 mm, sup-

plied) between the grounding point and ground terminal on the antenna unit. Coat

the hardware of the ground system with the supplied adhesive.

1.2 Antenna Unit (S-band Radar)

For installation considerations regarding the antenna unit, see section 1.1.1.

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.
