he RF cables on your AN/GRC-103 radio stick out about six inches from the radio.
That puts the cables in the line of foot traffic inside your commo shelter. That
means you could snag them when moving gear around.
If those cables get snagged hard enough, you’ll pull the wiring away from the con-
nectors. Then you have to send them off to DS for repair. That costs your unit time
and money.
Heat-shrink tubing, NSN 5970-00-926-2571 or 5970-00-959-6336, strengthens
the cable where the insulation and connector meet.
Cut off a 3-in length of tubing. Slip
it over the cable so that two inches of
tubing cover the insulation and one
inch covers the first section of the con-
nector. Then shrink the tubing with a
heat gun or blow dryer.
The tubing tightens around the cable
and reinforces it. The tubing also helps
protect the cable against moisture.

Even though you
have added this
