6. Attach shackles and four part web lifting sling
arrangement to the eyebolts.
7. Attach a suitable length tagline to one of the
eyebolts.
8. After hoisted into place the lifting eyes are to
be removed and replaced with the stainless
hardware that was removed in step 4 (the
eyes are galvanized with bare thread that will
rust if left exposed to the weather).
3.3.2. Install 76” Radome to mounting deck.
The antenna pedestal is shipped completely assembled, restrained for shipping, in its radome.
1. Man the tag line(s).
2. Remove four equally spaced bolts around the radome flange. Save these nuts and bolts to be re-
installed later.
3. 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 reinstalled after the
ADE has been installed.
4. Attach shackles and four part web lifting sling arrangement to the eyebolts.
5. Attach a suitable length tagline to one of the eyebolts.
6. Hoist the antenna assembly off the shipping pallet, by means of a suitably sized crane or derrick, to
allow access to bottom of radome assembly.
7. Open the hatch by pressing the round release button in the center of the black latches and gently
push the hatch up into the radome. Place the hatch door (gel coat surface up) inside the radome on
the far side of the antenna pedestal.
8. Inspect the pedestal assembly and reflector for signs of shipping damage.
9. Peel the paper off of the mounting pad (provided in the radome installation kit) to expose the sticky
side of the pad, align it to the mounting holes and press it in place on the underside of the radome
base.
10. Using Loctite 271, install the twelve mounting bolts (provided in 123549-2 mounting kit) into the
radome base.
ALL twelve mounting holes must be used when securing above decks
equipment to vessel.
11. Hoist the antenna assembly up onto the ship and hover above the mounting site on the ship.
12. Route AC power, ground strap/cable (see Grounding info below) and IF coax cables through the
cable passage in center of the bottom of the radome base and through the cable channel under the
lower base plate of antenna. Allow enough service loop to terminate these cables to the circuit
breaker assembly and connector bracket respectively (see cable termination information below).
13. Lower radome assembly into the mounting holes, positioned with the BOW reference of the radome
parallel with centerline of the ship. Any variation from actual alignment can be compensated with
the Home Flag Offset and AZIMUTH TRIM adjustment, so precise alignment is not required.
14. Using Loctite 271, install the twelve fender washers and hex nuts (provided in mounting kit) from
the underside of the mounting surface.
15. Remove the tag lines.
16. Remove the lifting sling.
17. Remove the four lifting eye nuts and reinstall the original perimeter bolt hardware (the eyes are
galvanized with bare thread that will rust if left exposed to the weather). Save the lifting eye
hardware in case lifting of the ADE is required in the future.
