3.4.2 Cable Pulling
The cable should be pulled manually, allowing sufficient slack in the
cable so that there is no tension on the cable or connectors when
installed. Do not snap" or apply sudden tension to the cable. Never
use a powered cable puller without consulting the cable
manufacturer and monitoring the pulling tension. High pulling
tensions, tightĆfitting conduits, and cable twisting can damage cable
shielding and insulation. This type of damage may not be found
through a physical inspection. It may require special cable testing
equipment to locate the damage. Refer to the cable manufacturer's
guidelines on cable pulling for more information.
3.4.3 Cable Termination
Cable stripping and crimping tools for RGĆ59/U cable are supplied by
all major connector manufacturers and are available from your local
electrical/electronic products distributors.
Use the following procedure to install the dual crimp plug connector
onto the coaxial cable:
Step 1.
After the cables have been installed in the conduit or cable
trays, slide the ferrule from the plug connector onto the
coaxial cable as shown in figure 3.8.

Step 2. Strip the coaxial cable using the dimensions shown in
figure 3.9. Be sure the shield braid wire is cut to the
correct length and cannot touch the center conductor.

Step 3. Place the center contact from the BNC plug connector,
assembled on the stripped conductor, in the partially
closed crimping dies as shown in figure 3.10. Be sure the
flange on the end of the center contact butts against the
crimping die.
