weight of your model antenna/radome and assure that equipment used to lift/hoist this
system is rated accordingly.
CAUTION:
The antenna/radome assembly is very light for its size and is subject to large
swaying motions if hoisted under windy conditions. Always ensure that tag lines, attached to
the radome base frame, are attended while the antenna assembly is being hoisted to its
assigned location aboard ship.

Read this entire assembly procedure before beginning.
Refer to the System Block diagram, General Assembly, Base Frame Assembly, Radome Assembly and
Radome Installation Arrangement drawings for your system.
We recommend that you place the crates in the area that you have chosen to assemble each of these major
components. It is recommended that you do not unpack the crates until you are ready to sub-assemble and
install the equipment.
