3. Refer to the radome assembly drawing. Observe the painted numbers on the radome panels that
clearly identify their positions respective to each other and the base pan assembly.
4. Loosely assemble the 6 lower side panels, using the hardware provided, to form the bottom half of
the radome. Do NOT tighten the bolts at this time. Open each seam wide enough to install a good
bead of silicone caulk, then firmly tighten all the bolts in that flange. Repeat until all flanges are
sealed.
5. Loosely assemble the 6 upper side panels, using the hardware provided, to form the upper half of the
radome. Do NOT tighten the bolts at this time. Open each seam wide enough to install a good bead
of silicone caulk, then firmly tighten all the bolts in that flange. Repeat until all flanges are sealed.
6. Apply a good bead of silicone caulk all the way around the top cap. Install the cap into the upper
radome panel assembly using the hardware provided and tighten all the bolts.
7. Set the lower half of the radome assembly on the base pan aligning the painted numbers on the
radome panels. Loosely attach the lower side panel assembly to the base frame using the hardware
provided. Do NOT tighten the bolts at this time. Lift the lower side panel assembly wide enough to
install a good bead of silicone caulk between it and the base pan, then firmly tighten all the bolts.
8. Fasten the antenna pedestal assembly, complete with base stand, to the base pan using the 1/2-13 x
1 1/2 (or the 3/8-16 x 1 1/2) inch bolts inserted from the bottom up and install a flat washer, a lock
washer and a nut in each mounting hole. Apply Loctite 271 and tighten securely.
9. Attach the antenna assembly (reflector, struts and feed) to the stabilized pedestal, by using the
reflector mounting hardware provided. Position the antenna over the four antenna support struts
(the antenna and the dish mounting clips are numbered or color coded make sure they match).
Insert the four mounting bolts, washers and nuts, apply Loctite 271 and tighten.
10. Attach the 15 pin connector on the antenna reflector harness to the shielded Polang Aux Relay box.
Connect the IF receive coax cables from the feed to the pedestal Modem or coax relay/switch panel
according to the block diagram.
11. Using a four point web lifting sling and lifting clips, lift the upper half of the radome up over the
antenna pedestal and set it onto the lower side panels aligning the painted numbers on the radome
panels. Loosely attach the upper and lower halves of the radome using the hardware provided. Do
NOT tighten the bolts at this time. Insert wedges between the upper side panel assembly and the
lower side panel assembly to hold open a space wide enough to install a good bead of silicone caulk
between it and the lower side panels, then remove the wedges and firmly tighten all the bolts.
12. Gently restrain the antenna prior to lifting the ADE onto the ship to restrict movement inside the
radome during the lift.
4.4.3.
Install Stow Braces, or other restraints, on the Antenna Pedestal. Attach shackles and web type lifting harness
to the four lifting holes in the base-frame.
Preparing the ADE for Lift
4.5. Installing The ADE
4.5.1. Hoist
WARNING: Hoisting with other than a webbed four-part sling may result in
catastrophic crushing of the radome. Refer to the specifications and drawings for the
fully assembled weight of your model Antenna/Radome and assure that equipment used
to lift/hoist this system is rated accordingly.
CAUTION: The antenna/radome assembly is very light for its size and is subject to
large swaying motions if hoisted under windy conditions. Always ensure that tag lines,
attached to the radome base frame, are attended while the antenna assembly is being
hoisted to its assigned location aboard ship.
