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.
Install 4 radome lifting brackets (PN 131514-2, shown here,
can be purchased separately), or other lifting arrangement,
to four opposite vertical flange mounting points (every
other vertical flange).
18. Hold the bracket under the bottom flange and
install a bolt and fender washer down through the
hole on one side of the vertical seam, through the
slot on that side of the bracket and tighten a nut
on the underside of the bracket
19. Install a second bolt and fender washer down
through the hole on the other side of the vertical
seam, through the slot on that side of the bracket
and tighten a nut on the underside of the bracket
NOTE: The excess length of the bolts serves as guide pins
when setting the top half of the radome onto the bottom
half. The nut on the underside serves as wedges to keep
the horizontal seam open to apply caulking.
20. Repeat steps 1 & 2 to install the other 3 brackets
under opposing flanges.
21. From the outside of the radome top, install
shackles and web lifting straps to the brackets.
NOTE: Let the person who was working inside the upper
half of the radome out.
The upper half of the radome is now ready to lift onto the
lower panels.
