Mounting platform side
Arrange a ground terminal as close as possible to Antenna Unit. There are two
methods to connect the ground wire for mounting platform side.
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.
1.2.2 FAR-2x38S Radars
How to assemble the Antenna Unit
The Antenna Unit consists of the antenna radiator (w/antenna support) and the anten-
na unit chassis, and they are packed separately. Fasten the antenna radiator to the
Antenna Unit chassis as follows:
1. Remove the protective waveguide
cap from the waveguide on the radia-
tor bracket.
