3.4. Installing The ADE
3.4.1. Hoist
WARNING:
Hoisting without 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.
4. Assure that the antenna is restrained before hoisting. Check that all nuts on the base frame assembly
are tightened according the torque values listed below:
5. Using a four-part lifting sling, and with a tag line attached to the radome base frame, hoist the
antenna assembly to its assigned location aboard ship by means of a suitably-sized crane or derrick.
6. The radome assembly should be positioned with the BOW marker aligned as close as possible to the
ship centerline. Any variation from actual alignment can be compensated with the AZIMUTH TRIM
adjustment in the ACU, so precise alignment is not required.
3.4.2. Install Antenna/Radome/Baseframe
Bolt, or weld, the legs of the radome base frame directly to the ship's deck. If the deck is uneven or not level,
weld clips to the deck and attach them to the legs of the radome base frame. When completed the radome
base must be level.
