2. Attach a four-part lifting sling to the four lifting eyes in the
base of the radome and lift the radome assembly free of
its shipping pallet. Place the radome assembly on
temporary support blocks at least 22 inches high.
3. Loosely assemble the radome base frame's eight legs and
eleven braces as shown in the Radome Base Frame
Assembly drawing using the hardware provided. Insure
that a split washer is used under each nut. When
assembled, apply Loctite and tighten all hardware.
4. Using the 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.
5. 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 Home Flag Offset and AZIMUTH
TRIM adjustment in the ACU, so precise alignment is not required.
6. Bolt or weld the legs of the radome base frame directly to the ship's deck or suitable mounting
surface. 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 should be as near to level as is practical.
7. Disconnect the lifting sling from the four lifting eyes in the base of the radome.
8. Remove the 4 lifting eye bolts. Save the lifting eye hardware in case lifting of the ADE is required in
the future.
9. Route AC Power and IF coax cables through the strain reliefs installed in the basepan of the radome.
Allow enough service loop to terminate these cables to the circuit breaker assembly and connector
bracket respectively (see cable termination information below).
3.4. Cable Installation
3.4.1. Shipboard Cable Installation
CAUTION: Rough handling, tight bending, kinking, crushing and other careless
handling of the cables and their connectors can cause severe damage.
The cables must be routed from the above-decks equipment mounting location through the deck and
through various ship spaces to the vicinity of the below-decks equipment. When pulling the cables in place,
avoid sharp bends, kinking, and the use of excessive force. After placement, seal the deck penetration glands
and tie the cables securely in place all along the cable run(s).
3.4.2.
The TX, RX and AC Power cables must were routed through the cable strain relief in a previous step.
Cable Terminations In The 81 inch Radome
1. Route and tie the cables together with the pedestal cables to provide some service loop length
inside the radome.
2. Route AC Power cable through the clamp in the end of the breaker box and terminated to the
breaker screw terminals.
3. Tighten the clamp in the end of the breaker box.
4. Connect the TX IF cable from below decks to the “TX” connection on the bracket.
5. Connect the RX IF cable from below decks to the “RX” connection on the bracket.
6. Apply RTV to the strain relief joints and tighten the compression fittings to make them splash proof.
3.5. Installing the Below Decks Equipment.
Installing the Antenna Control Unit, Base Multiplexer Panel and the Terminal Mounting Strip.
