LABEL WIRE ENDS, ITEM 2 OF DRAWING 8628190, AND JUMPER WIRES, ITEM 13, AS SHOWN ON SHEET 5, USING LABELS, ITEMS 16 AND 15 RESPECTIVELY. SEE6.

TABLE A ON SHEET 2 FOR PROPER WIRE CONNECTIONS.

PROCESS OF CONNECTING LITZ WIRE TO JUMPER WIRE CONNECTOR:7.

CUT END OF LITZ WIRE, ITEM 2 OF DRAWING 8628190, SO THAT THE ENDS OF WIRES 1, 2 AND 4 ARE 6 INCHES FROM THE CONNECTOR, ITEM 8, AND THE END OF WIRE 3

IS 3 INCHES FROM THE CONNECTOR, ITEM 8, AS SHOWN ON SHEET 5.

PULL AWAY BY HAND THE STRINGY OVERWRAP OF LITZ WIRE SO THAT 1.5 INCHES OF LITZ WIRE IS EXPOSED.

ENSURE THAT THE STRANDS OF THE LAST INCH OF LITZ WIRE ARE NEAT AND HAVE MAXIMUM CONTACT WITH ONE ANOTHER.

USING A COMMERCIAL OFF-THE-SHELF SOLDER POT, ITEM 19, HEAT SOLDER, ITEM 17, TO 800 °F.

DIP THE END OF THE LITZ WIRE (1.0 INCH +0.1/-0.0 INCH) INTO THE SOLDER FOR 10 SECONDS (FLUX IS NOT REQUIRED).

WHEN ALL FOUR LITZ WIRE ENDS HAVE BEEN SOLDERED AND ALLOWED TO COOL, PERFORM INDUCTANCE P1 TEST AND CONTINUITY P1 TEST AS DETAILED IN DWG 8628196, VLF/LF LOOP ANTENNA ASSEMBLY QA TEST PROCEDURES.

INSERT THE LITZ WIRE ENDS INTO THE MALE/PIN CONNECTORS, ITEM 11, AND CRIMP PER MANUFACTURER'S INSTRUCTIONS.

BACKFILL THE CONNECTOR CUPS, WHERE THE CRIMPS CONTACT THE LITZ WIRE, WITH TERMINAL SOLDER, ITEM 18, USING A HANDHELD SOLDER IRON (MINIMUM 240 WATTS).

PROCESS OF CONNECTING JUMPER WIRE TO JUMPER WIRE CONNECTOR AND TO ANTENNA CONNECTOR:

STARTING WITH A 9 INCH LENGTH OF JUMPER WIRE, ITEM 13, STRIP ONE END 0.59 INCHES.

INSERT THE STRIPPED WIRE END INTO THE FEMALE/SOCKET CONNECTOR, ITEM 12, AND CRIMP PER MANUFACTURER'S INSTRUCTIONS.

BACKFILL THE CONNECTOR CUP WITH THE TERMINAL SOLDER, ITEM 18.

ENSURE THE CONNECTORS, ITEMS 11 AND 12, AS WELL AS ANY NEARBY WIRES ARE COOLED TO ROOM TEMPERATURE.

SLIDE A 3.0 INCH LENGTH OF HEAT SHRINK, ITEM 14, OVER THE PIN/MALE CONTACT, ITEM 11.

CONNECT THE PIN CONNECTOR, ITEM 11, TO THE SOCKET CONNECTOR, ITEM 12.

SLIDE THE HEAT SHRINK, ITEM 14, OVER THE CONNECTORS, ITEMS 11 AND 12, AND CENTER IT ON THE MATING LOCATION.

AWAY FROM THE SUPPORT BLOCK, ITEM 2, USE A HEAT GUN, AS SPECIFIED BY THE MANUFACTURER, TO SHRINK THE HEAT SHRINK, ITEM 14, TO THE WIRES AND

CONNECTORS, AS DETAILED ON SHEET 5.

THREAD AND HAND TIGHTEN THE ANTENNA CONNECTOR, ITEM 8, INTO THE SUPPORT BLOCK, ITEM 2, WITH O-RINGS, ITEMS 9 AMD 10, INSTALLED; AS SHOWN IN SECTION B-

B ON SHEET 4. USE O-RING GREASE, ITEM 20, AS NECESSARY.

LAY THE WIRE ASSEMBLY INTO ITS PROPER LOCATION IN THE SUPPORT BLOCK GROOVES SUCH THAT THE JUMPER WIRE, ITEM 13, IS PASSING OVER THE CONNECTOR, ITEM 8.

LOCATE THE POINT ON THE JUMPER WIRE, ITEM 13, THAT IS DIRECTLY ABOVE THE APPROPRIATE ANTENNA CONNECTOR SOLDER CUP, ITEM 8.

BEND THE JUMPER WIRE, ITEM 13, TO THE APPROPRIATE SOLDER CUP OF THE ANTENNA CONNECTOR, ITEM 8, AS SPECIFIED IN TABLE A ON SHEET 2.

CUT THE END OF THE JUMPER WIRE, ITEM 13, SO THAT THERE IS .57 INCHES OF WIRE BETWEEN THE BEND AND THE END OF THE WIRE.

STRIP 0.35 INCHES OF THE INSULATION FROM THE WIRE END.

INSERT THE STRIPPED WIRE INTO THE SOLDER CUP AND SOLDER USING THE TERMINAL SOLDER, ITEM 18.

REPEAT THE STEPS ABOVE FOR ALL FOUR JUMPER WIRES, ITEM 13.

AFTER ALL FOUR JUMPER WIRES, ITEM 13, HAVE BEEN SOLDERED INTO THE ANTENNA CONNECTOR, ITEM 8, ENSURE THAT THERE ARE NO SOLDER BLOBS IN-BETWEEN THE

SOLDER CUPS OF THE ANTENNA CONNECTOR, ITEM 8.

PRE-POTTING TESTING:

PERFORM INDUCTANCE P2 TEST, CONTINUITY P2 TEST, AND POLARITY P2 TEST AS DETAILED IN DWG 8628196, VLF/LF LOOP ANTENNA ASSEMBLY QA TEST PROCEDURES.

UPON SUCCESSFUL COMPLETION OF THE QA TESTS, ENCAPSULATE THE ENTIRE ASSEMBLY WITH POTTING COMPOUND, ITEM 5.

IN ORDER TO MAINTAIN MAGNETIC PROPERTIES, THE FERRITE BARS, DWG 8628194, SHALL NOT BE HEATED ABOVE THE CURIE TEMPERATURE OF 170 C.

ENCAPSULATED AREAS SHALL BE FREE OF LARGE BUBBLES AND ENTIRE ASSEMBLY SHALL MAINTAIN MINIMUM HYDROSTATIC INTEGRITY WHEN DEPLOYED.

AIR BUBBLES, POCKETS, OR VOIDS SHALL BE PERMISSIBLE IF NOT MORE THAN 3.2MM (1/8IN) IN DIAMETER AND NOT CLOSER THAN 1.6MM (1/16IN) TO CONDUCTOR TERMINATIONS OR MOLD OUTER SURFACE. THERE SHALL BE NO MORE THAN FIVE VISIBLE BUBBLES AS DESCRIBED ABOVE PER CUBIC INCH.

POST-POTTING ASSEMBLY:

REMOVE ALL BURRS AND BREAK SHARP EDGES R.03-.25 OR CHAMFER.

PERFORM INDUCTANCE P3 TEST, CONTINUITY P3 TEST, AND POLARITY P3 TEST AS DETAILED IN DWG 8628196, VLF/LF LOOP ANTENNA ASSEMBLY QA TEST PROCEDURES.

BORE OUT THE HOLE AS SHOWN IN DETAIL E ON SHEET 4.

APPLY O-RING LUBE, ITEM 20 TO O-RING, ITEM 6 AND INSTALL O-RING INTO LIFTING INSERTS, ITEM 3.

PRESS EACH LIFTING INSERT, ITEM 3, ONE AT A TIME, INTO THE BORED HOLES OF THE

POTTING COMPOUND, ITEM 5.

FOR LIFTING, REFER TO OUTLINE AND INSTALLATION DRAWING, 8628200.

AFTER ASSEMBLY INSTALL CAP, ITEM 7, TO PROTECT CONNECTOR, ITEM 8. 8.

THE COMPLETED ANTENNA ASSEMBLY SHALL WEIGH 145 20 LBS.9.
