Installation Sea Tel Tracker 6000
3.7. Closing the Radome
1. Attach the 4-part lifting sling to the lifting straps around the base of the upper radome
assembly (approx. 1500 lbs).
2. Attach at least 2 tag lines to 2 opposite lifting straps to control the upper radome assembly
while it is hoisted.
3. Using a suitably rated derrick or crane, lift the upper radome assembly above the antenna
assembly and move into position to set the upper radome assembly onto the radome base
assembly.
4. Exercise extreme caution to assure that the upper radome assembly does not damage the
feed tube or reflector as it is lowered down to within several inches of the top of the radome
base section.
5. Rotate the upper radome assembly to align panel 401 to be in place directly above panel 501.
6. Continue lowering the upper radome assembly, while guiding it to be properly aligned with
panel 401 centered directly atop panel 501 and suspended ¼ inch above the radome base
section.
7. While holding the upper radome assembly suspended, loosely install the horizontal flange
mounting bolts and washers. Apply Loctite to the exposed threads of the bolts, and with the
flange slightly open apply a bead of caulking between the panels. Lower the upper radome
assembly until it is sitting on the radome base section and tighten to torque spec the bolts.
Wipe off the excess caulking from inside and outside of the horizontal panel flange mating.
8. Remove the 4-part lifting sling from the radome assembly.
