3.7. Assembling the ADE
3.7.1. Preparing for Assembly of the ADE
Read this entire assembly procedure before beginning.
Refer to the System Block diagram, General Assembly, Baseframe Assembly, Radome Assembly and
Radome Installation Arrangement drawings for your system.
Select a secure assembly site that provides enough area to work with the large radome panels while sub-
assembling the baseframe, sections of the radome, Antenna Pedestal and Reflector & Feed. The area
should be a clean, flat location, free of rocks & debris (ie concrete). The site should also provide
protection from wind, rain and other adverse weather. A hoist, or small crane, is needed to assemble
these sub-assemblies to form the final ADE Assembly.
As an example, you might sub-assemble everything on the pier where the ship will tie up, then use the
crane to put the sub-assemblies together and lift the whole ADE up to the mounting location on the ship.
You can change order of these steps, however, in the end the objective is to have a well
sealed radome with flanges that are clean of excess caulking. In addition it is important that
the ADE is structurally sound for severe weather conditions.
3.7.2. Sub-assemble the Base Frame Assembly
Refer to the Base Frame Assembly drawing for your system and the procedure below.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 2760 or its equivalent.

the tightening torque values listed below:
