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.
4.4.7. Close the 144” Radome Assembly
Refer to the Radome Assembly drawing for your system and the procedure below.
1. Hoist the upper section of the radome up over
the reflector & feed assembly and set it down
onto the lower section of the radome.
NOTE: The bolts protruding down out of the lifting
brackets will act like guide pins to align into the holes in
the top of the riser panels. Make sure you align the
vertical seams of the upper & lower sections of the
radome.
NOTE: The brackets themselves will act as spacers to
allow the caulking to be applied in the horizontal seam
between these two sections of the radome.
2. Loosely install all of the bolts, fender washers
and nuts to attach the upper panels to the
using the hardware provided. Do NOT tighten
the bolts at this time.
3. Start injecting caulking midway between two
brackets.
4. When close to the bracket you are caulking
toward, remove the bracket and install
hardware in the two vacant holes where the
bracket was (make sure you keep the original
hardware with the bracket).
