Sea Tel 9711-56 IMA Installation in 144” Radome
4-23
EAR Controlled - ECCN EAR99
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).
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.
