Sea Tel 2400 Dual Band C/Ku Installation in 144” Radome
4-25
EAR Controlled - ECCN EAR99
1. If not already done, enter the ADE and
stow the antenna pedestal using the Stow
Kit (provided) and the instruction in the
Maintenance section of the antenna
manual.
2. Attach the swivel eye-bolts of the Lift-It
144” lifting harness (or eye-bolts or
shackles and web straps properly rated for
the weight to be lifted) to four of the 8
“Lift Here” lifting point holes around the
perimeter of the Base Frame.
3. Attach appropriate length of rope tag lines
to the Base Frame.
4. If not already accomplished, remove the
shipping bolts that mount the base frame
to the pallet.
5. Discard this hardware.
The ADE is now ready to hoist onto the ship.
4.6. I nstalling The ADE
WARNI NG:
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.
CAUTI ON:
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.
4.6.1. Hoist the ADE
1. Assure that the antenna is stowed/restrained before hoisting.
2. Using the lifting harness arrangement previously described hoist the antenna assembly to its
assigned location aboard ship by means of a suitably-sized crane or derrick.
3. 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 antenna control unit, so precise alignment is not required.
4. Bolt, or weld, the feet of the base frame to the mounting surface aboard the ship.
4.6.2. Connecting the ADE
Refer to the System Block diagram, the Antenna Schematic and the general strain relief installation
information in the drawings for this terminal.
Refer to Cable information in the Specifications chapter for multi-Conductor and IF cable information.
Route the IF Cables and the AC Power cables to the location where they will enter the radome through
strain reliefs.
Sea Tel recommends that separate, dedicated, 220 VAC Power be provided for the Marine Air
Conditioner.
Do NOT combine this with the 220 VAC Power provided for the Antenna Pedestal and RF Equipment.
