3.3. Installing the ADE
The antenna pedestal is shipped completely assembled in its radome. Please refer to the entire Site Survey chapter of
this manual.
Base Hatch Access
- Mounting the radome directly on the deck, or
platform prevents access to the hatch in the base of the radome unless an
opening is designed into the mounting surface to allow such entry. If there is
no access to the hatch the only way to service the antenna is to remove the
radome top. Two people are required to take the top off of the radome
without cracking or losing control of it, but even with two people a gust of
wind may cause them to lose control and the radome top may be
catastrophically damaged (see repair information in the radome
specifications) or lost.
If access to the hatch cannot be provided in the mounting surface, provide a
short ADE mounting stanchion to mount the ADE on which is tall enough to
allow access into the radome via the hatch.
Ladder rungs must be provided on all mounting stanchions greater than 3-4
feet tall to allow footing for personnel safety when entering the hatch of the
radome.
Cable Passage -
The radome base is designed with a bottom center cable
passage and Roxtec® Multidiameter® blocks for cable strain relief. The
recommended cable passage in the 50, 60 and 66 inch radomes is through the
bottom center of the radome base, down through the ADE mounting
stanchion, through the deck and into the interior of the ship.
Bottom center cable passage is recommended, however, a strain relief kit is provided with the system if off-center
cable entry is required.
Note: Strain relief installation procedure, provided in the Drawings chapter, MUST
be followed to assure that the cored holes are properly sealed to prevent moisture absorption and de-
lamination of the radome base.
3.3.1. Prepare the 50”, 60”, 66” or 76” Radome Assembly
1. Remove the side walls of the Radome crate.
2. Lift the pallet using a forklift and/or jacks.
3. From the under side of the pallet, remove the
4 shipping bolts which attach the ADE to its’
pallet. Discard this shipping hardware.
4. Remove four equally spaced bolts around the
radome flange. Save these nuts and bolts to
be re-installed later.
5. Install four lifting eyebolts in the vacant holes
in the flange of the radome.. (Hardware
provided in the radome installation kit). Keep
the original perimeter bolt hardware to be re-
installed after the ADE has been installed.
