3.7.7. 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).
NOTE: It is extremely important to assure that the flanges
are properly aligned before the bolts are tightened and kept
in alignment as the hardware is aligned. This is necessary
for the inside clearance and the outside aesthetic
appearance of the radome. Please note this picture shown
good alignment as observed from inside the radome and
below a flange with bad alignment.
