1.
Attach the Shield Block(s) (2) to the backshell (1) by inserting the flathead screws (3) through the
holes on the Shield Block and threading into the tapped holes on the backshell (1). (See Figure 11-1).
The appropriate number of Shield Block kits is included in the GWX 68 connector kit.

2.
At one end of a shielded cable (4) measure back a distance between “Window Min” to “Window
Max” (Table 11-6) and cut a window (max size 0.35”) in the jacket to expose the shield. (See
Figure 11-2). Use caution when cutting the jacket to avoid damaging the individual braids of the
shield. When dealing with a densely populated connector with many cables it may prove beneficial to
stagger the windows throughout the “Window Min” to “Window Max” range. If staggering is not
needed the “Ideal Window” length is recommended.
Tools needed to Accomplish the Window Cut:
•
Coaxial Cable Stripper
•
Thermal
Stripper
•
Sharp Razor Blade
3.
Connect a Flat Braid (6) to the shield exposed through the window of the prepared cable assembly
(4). The Flat Braid goes out the front of the termination towards the connector. Do not allow wires
to exit the rear of the termination and loop back towards the connector. (See Figure 11-2). Make this
connection using an approved shield termination technique. Refer to FAA Advisory Circular AC
43.13 as a reference for termination techniques.
