6. Open each 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).
7. Clean excess caulking off of the flange areas
inside and outside the radome.
8. Repeat caulking, closing and cleaning the
vertical flanges until all of the upper panel
seams are closed.
9. Remove tape from the vertical seams.
10. Apply a 3/8” layer of caulking to the under-
side of the perimeter flange of radome cap.
11. (Outside person) Climb onto the upper panel
assembly, have someone (third person
required only for this step) hand the cap to
the person on top of the radome.
12. Insert the cap into the top of the radome with
a twisting rotation. This will evenly spread
the caulking and align the bolt holes inside
the radome top (coordinate with the person
inside the radome).
13. (Inside Person) Install the radome cap using
the provided hardware. CAUTION: Do NOT
over tighten the hardware. Only tighten until
the fiberglass STARTS to flex.
14. Apply additional caulking to fill gaps between
the upper panels and the cap.
15. Clean off excess caulking.
16. The upper section of the radome is now
complete.
17. Place short pieces of 2”x4” boards under the
perimeter of the radome top to raise it up off
of the ground.
