COMMUNICATIONS SYSTEM
Procedural Steps (Cont):
2. Alternate repair to coaxial cables Damage to coaxial cable shields or the center
conductors can be repaired using the same methods as any other shielded wire repair.
Insure that this repair is sufficiently insulated to prevent the center conductor from
shorting to the shield. The shielding may be restored by several methods. One such
method is illustrated below.
a. Remove 1/2 inch of insulation from the shielding and join the severed ends of
the shielding together by wrapping a conductive material over the repair. Some
suitable materials are tubular copper braid, metal gauze, conductive foil from gum
wrappers, cigarette packages or common kitchen foil.
b. Remove one inch of insulation, unravel exposed shielding, and twist into
pigtails. Join the pigtails by splicing in a piece of insulated wire. Insulate the entire
repair when using either method of repair.
3. Record the BDAR action taken. When the mission is complete, as soon as
practicable, repair vehicle using standard maintenance procedures.
