8. Use small wedges to open a vertical seam wide
enough to install a good bead of silicone caulk.
Working from top to bottom apply Loctite to
and then firmly tighten all of the bolts in that
seam (smaller dual beads of caulking can be
applied from outside and inside if you prefer).
9. Clean excess caulking off of the flange area
(inside and out). The empty caulking tubes can
be used to clean off the excess caulk without
scratching the radome finish.
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.
4.4.6. 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.
