How To Crimp CATV Compression Connectors (F, BNC, RCA)

This guide will explain how to create your own coax cable using compression style CATV connectors. This process will work for F, BNC, and RCA style connectors. The same techniques can be used on various sized cables. We will be using RG6 cable and RG6 F-type Compression Connectors, which come included in the 902-340 CATV “F” Compression Tool Bundle.

Step 1 – Spool out your length of cable
Pull out enough cable to run the length required for your installation. Make sure the ends are cut flush.

Step 2 – Strip cable to center conductor
Insert the cable into the stripper cavity that is designed to remove all layers of the cable except the center conductor. This cavity is easy to identify as it has a notch for the conductor. Line up the cutting blade so it is at 1/4″ away from the flush end of the cable. In a circular motion rotate the stripper around the coax cable. After a few rotations the dielectric insulator, foil shield, braid and outer jacket should come off with ease. You should now have 1/4″ of conductor exposed at the end of your cable


Step 3 – Strip only the outer jacket
Use the other cavity to strip only the outer jacket 1/4″ away from where the conductor is now exposed. Use the same rotary motion as the previous step to remove the jacket from the cable. You should now have roughly half an inch of cable stripped to these two stages.

Step 4 – Fold braided shield back
Fold the braided shield over the outer jacket and away from the dielectric insulator. This will leave the 1/4″ dielectric wrapped in foil shield and another 1/4″ of center conductor exposed.

Step 5 – Insert the cable into the compression connector
Use moderate force and push the cable all the way into the connector. You need to make sure the cable is in completely or the crimp may not work correctly.



Step 6 – Crimp the connector on to the cable
Insert the connector into the adapter piece on the crimp tool and have the base of the connector rest on top of the metal stop plates. These plates will keep the connector in place during the crimp process. Squeeze the handles together until the full range of crimp motion has been completed. You can now open the tool and remove the crimped end of the cable. Give the connector a good tug to ensure it is securely in place.
If crimping BNC or RCA then do NOT use the included adapter with the compression crimp tool!

Step 7 – Crimp the other end of the cable
Repeat steps 1 through 6 on the other end of the cable.

How to Create a Network Cable

The following procedure goes over creating your own Ethernet cable. This process can be used to create both Category 5 & 6 cables. In this demonstration we used the 902-351 DIY Crimp Bundle. This is the perfect assortment of tools for someone learning to make their own network cables.



Step 1 – Spool out your length of cable
Pull out enough cable to run the length required for your installation. Be sure to allow enough to trim several inches off each end. It’s always better to go a little longer than to not have enough cable!



Step 2 – Strip off the outer jacket
Insert the cable into your wire stripper. In this demonstration we are using a round Cat 5 cable. If you use a flat cable then you need to use a stripper for flat cable. Most strippers designed for creating network cables can do either cable type. Rotate the stripper around the cable until the entire circumference of the jacket has been cut. Inspect the inner wires to make sure none of them have been nicked. If any are showing exposed copper wire then you need adjust your blade depth and try again.



Step 3 – Separate your wire pairs
Untwist all 4 pairs of wires and straighten them out the best you can. If there are any white fibers or a plastic divider in the center you can now trim it off.



Step 4 – Arrange wires according to diagram
Line up the individual wires in the order shown on your diagram. In our example we used the common Wiring Diagram B layout. Use your thumb and index finger to straighten out all the individual wires, while keeping a good grip to keep them in order.



Step 5 – Cut the wires
Cut the wires flush about 1/2″ from where the jacket was stripped off the cable. Make sure to leave enough that the ends of the wires are able to reach the pins of the connectors. The cable needs to go inside the connector housing enough for the crimp tab to come down on top of the jacket and hold it in place.



Step 6 – Insert wires into connector
Insert the wires into the connector. Make sure the connector is oriented properly, the release tab should be facing down toward the ground. Ensure all wires are still in the correct order after they are pushed all the way to the pins.



Step 7 – Crimp the connector
Insert your connector with the wire inside the 8P8C slot of your crimp tool. Give the crimp tool a good squeeze to ensure it goes through the full range of motion and creates a proper crimp. Pull your connector out of the crimp tool to show your finished connector. Repeat all of these steps to crimp a connector on the other end of your cable.



Optional: Test your cable
Use a modular/LAN cable tester to ensure all 8 wires are making connection.
