Sea Tel 9711-56 IMA Installation in 144” Radome

EAR Controlled - ECCN EAR99
assembled very quickly. With three bolts loosely holding each flange the radome will then stand as a
loose bowl and the extra 5 people can leave. Loosely install the rest of the hardware in each flange.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled with
Loctite 2760 or its equivalent.
1. On a flat surface, adjoin two panels (one
should be the panel with the door in it) and
loosely install hardware in all of the holes in
the adjoined vertical flanges. Do NOT tighten
the bolts at this time.
HINT: A crate, or other object, can be put against the
panels to hold them up while additional panes are
adjoined.
2. Assure good horizontal alignment of the
panels. Good alignment of the bottom edge
of the panels is important for good seal on the
base frame and good alignment of the top
provides a good seal between the lower and
upper panels.
3. To provide a clean caulked seam all around
the panels: apply painters’ masking tape to
the outside perimeter of each of the panels
about ¼” from the top, bottom, left and right
edges at each flange joint. The tape will be
removed just before the radome caulking has
had time to set.
NOTE: It is extremely important to assure that the
flanges are properly aligned before the bolts are
tightened and kept in alignment as the hardware is
aligned. This is necessary for the inside clearance and
the outside aesthetic appearance of the radome.
Please note this picture shown good alignment as
observed from inside the radome and below a flange
with bad alignment.
