10. Repeat caulking, closing and cleaning the vertical
flanges until all of the lower panel vertical seams
are closed.
11. Remove the tape from the vertical seams.
12. Insert small wedges between the lower radome
panes and the base pan.
13. Start injecting caulking near one wedge.
14. When close to the wedge you are caulking toward,
remove it and continue caulking toward the next
wedge.
15. Quickly continue caulking toward the next wedge
until all of the wedges have been removed and
caulking of the entire horizontal seam is
completed.
16. Apply Loctite to and firmly tighten all of the
horizontal seam bolts.
17. Clean excess caulking off inside and outside of the
radome.
18. Remove tape from the horizontal edges of the
lower panels.
The bottom half of the radome is complete. Next
you will assemble the top half and then install it on
this lower half.
3.7.5. Sub-assemble the upper panels of the 144” 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 (ie concrete)
to assure good horizontal alignment of the panels.
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 2760 or its equivalent.
Only 2 people are required to sub-assemble the top of the
radome.
1. On a flat surface, adjoin two panels and loosely
install a bolt/nut high, mid and low in the adjoined
flange.
2. Continue adjoining additional panels loosely
installing a bolt/nut high, mid and low on each
flange until all six panels have been loosely
assembled to form the bottom half of the radome.
3. The person inside now loosely installs the rest of
the hardware in all of the flanges. Do NOT tighten
the bolts at this time.
NOTE: The person who is working inside installing
hardware, applying Loctite, tightening hardware and
cleaning the inner flanges will remain inside until the cap
and lifting brackets are installed.
4. Assure good horizontal alignment of the panels.
Good alignment of the bottom edge of the panels
is important for good seal between the lower and
upper panels.
