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 3-1).
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 3-5) and cut a window (max size 0.35”) in the jacket to expose the shield. (See Figure
3-2). 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 3-2). Make this
connection using an approved shield termination technique. Refer to FAA Advisory Circular AC
43.13 as a reference for termination techniques.
