1. Place the radome base frame
on temporary support blocks,
or jack stands, at least 22
inches high.
2. Loosely assemble the eight
legs, eight interior braces and
four outer braces from the
underside of the radome base
frame to the
second hole
in
the bottom end of the legs
using the hardware provided.
Insure that a split washer is
used under each nut.
3. Assure that the legs and
braces are correctly
assembled.
4. Apply Loctite to the bolt
threads and tighten all the
hardware to specified torque.
5. Remove the support blocks, or
jacks, and set the base frame
down on the flat, even,
assembly surface to align the
feet. Apply Loctite and
tighten all the hardware to
specified torque.
6. Install the Base Hatch and
clamp the latches from the
under-side.
3.8.3. Sub-assemble the bottom panels of the 126” Radome Assembly
Refer to the Radome Assembly drawing for your system and the procedure below. It is best to have
at least
TWO people sub-assembling the radome, one working from the inside and the other outside. Sub-assemble
the sections of the radome on a clean, flat location that is free of rocks and debris (i.e. concrete) to assure
good horizontal alignment of the panels.
If there are a sufficient number of people available to each hold a panel while an additional person loosely
installs a bolt/nut high, mid and low on each flange, the bottom half of the radome can be 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.
