Step 10. Holdthe assembly in place andclose the crimp tool
handles until the rachet releases.
Step 11. Remove the crimpedassembly from the crimping dies.
The connector is now attachedto the coaxial cable. See

3.4.4 Cable Segment Testing
Once a cable segment has been terminatedwith a connector on
each end, visually inspect the connector for loose connections,
nickedinsulation, or loose strands from the braidthat might cause a
poor connection or short. The center contact shouldbe straight and
centered inside the connector dielectric. Be sure that the center
conductor is inserted deep enough into the connector body. The tip
of the center contact shouldbe approximately even with the endof
the connector dielectric. Be sure the ferrule is crimped tightly against
the body of the connector andthat the shieldbraidwire does not
protrude from the ferrule.
Check the cable's mechanical connections by grasping the outer
conductor connector in one handandthe coaxial jacket in the other.
Pull firmly. The connectors should hold. Use a time domain
reflectometer to test for cable damage, shorts, and discontinuities.
