Refer to the following procedure for instructions on how to attach the various
electrical connectors to a dropline.
To attach an electrical connector to a dropline, follow these steps:
1.
Cut the Belden 9463 twinaxial cable to the length desired for a dropline.
Important: Remember, a dropline must be no more than 100 feet (30.5 meters)
in length. If possible, keep the dropline cables longer than 10 feet (3.0 meters)
in length. Refer to ‘‘Determining Cable Length” in Chapter 2 for guidelines on
determining appropriate cable lengths.
2.
Slip the large-diameter piece of shrink tubing over one end of the dropline.
3.
Using wire strippers, remove 1 inch (25.4 mm) of the outer jacket from the
same end of the dropline.
Important: In the next step, do not cut the drain wire.
4.
Using wire cutters, remove the exposed portions of the foil shield, braided
shield, and filler cords from the cable.
5.
Remove 0.125 inch (3.2 mm) of insulation from the end of each
conductor wire.
