The following is a 3 step guide on how to install BNC connector onto coax cable, using 1-piece BNC connector (it is called twist-on BNC). There are also 2-piece and 3-piece BNC connectors, but the advantage of this method is you don't need a crimping tool which is rather difficult to handle; the twist-on BNC connection is very stable and effective as long as you follow the right steps with proper tools. Coax cable installing shouldn't result in any injuries when followed correctly; always safely store the cutters and do not use regular blade to strip the wire.


STEP 1: PREPARE CABLE
coax cable, from PelikanCam.com Cut the coax cable. Use a proper cable cutter.
coax stripper, from PelikanCam.com Adjust the depth of blades of the stripper (refer to the manual). Insert coax cable into the stripper, leaving about 1/8" of exposed cable. Make sure the tool is set for the right size of "59" which will be seen on the top hole. Rotate the tool clockwise sufficiently enough to obtain a good strip. Squeeze handles to remove stripper from cable.

coax cable, from PelikanCam.com Remove the waste material from strip and expose the cable.
coax cable, from PelikanCam.com Remove the PVC jacket. Be careful not to take out the copper braid.
coax cable, from PelikanCam.com Twist the outer braid in a clockwise direction in such a manner that about 1/8 inch of inner dielectric foam is bared, and the braid is left flat. Stray or loose braid, especially if it touches the center conductor, can cause shorts.
 
STEP 2: ASSEMBLE BNC CONNECTOR
coax cable, from PelikanCam.com Gently insert the center conductor down into the back end of the twist-on BNC connector, feeling it into the guide hole, firmly push the cable home as far as possible, then screw the connector onto the cable in a clockwise direction until it stops.

coax cable, from PelikanCam.com Visually inspect the connection; make sure no braiding is exposed and the BNC connector is firmly attached to the cable. Now you have finished one end and make the other end with the same process.
 
STEP 3: TEST THE CABLE
coax cable, from PelikanCam.com A test terminator comes with the tester.
coax cable, from PelikanCam.com Install test terminator onto one end of a cable run.

coax cable, from PelikanCam.com Install tester onto the opposite end of cable to be tested. Press the test button. Tester will indicate if the cable is "GOOD", "BAD", or "OPEN".
