17. Leave a gracious service loop
in the yellow receive coax and
connect it to the Co-Pol LNB.
This loop is required to allow
the feed to rotate through its
full 270 degree (+/- 135)
range of rotation.
18. Leave a small service loop in
the feed harness and connect
it to the IDC connector. This
harness does not rotate with
the feed during rotation.
19. On the back side of the
reflector, route and connect
the harness to the “Feed”
DB25 port on the PCU as
required.
20. On the back side of the
reflector, route the Cross-Pol
LNB coax (orange) to the J1
(NC) connector of the coax
switch on top of the PCU.
21. On the back side of the
reflector, route the Co-Pol
LNB coax (yellow) to the J2
(NO) connector of the coax

3.3. Assembling the ADE
3.3.1. 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.
