You can DIY Coaxial Patch Cords From Now on

Materials:
The first and most important material we will be using is the cable.
coaxial cable is available in a variety of different types typically categorized by the military Radio Guide (RG-) specs. The most common ones are listed below:

RG59/U Coaxial Cable (75 Ohms cable)
Typically used for low-power video such as baseband video for closed circuit television and RF signal connections. While RG-59 will support high quality television and video signals, it only does over short distances. As a result, this type of coaxial cable is used for connecting VCR's and the like to television sets. The longer distance runs have been replaced by either RG-6 or RG-11.

RG6/U/UQ Coaxial Cable(75 Ohms cable)
This is the coaxial cable of choice for cable television, satellite television, cable modems and the like because it exhibits low loss at high frequencies. RG-6 is often sold in either RG-6/U double sheilded, or RG-6/UQ quad shielded varieties. This type of coax is also used for serial device interface (SDI) signals.

Other Materials you need:

Coaxial Connectors (F connector ect. which you need as per your application)

Coaxial Cable stripper

Step 1: Cut the cable so that the end of the cable is nice and clean. Then, after adjusting the cable stripper for your cable type, clip the stripper onto the end of the cable as shown below. You may first test the stripper on a scrap piece of cable to make sure the blade is set at the proper height and not cutting through the shielding / ground wire where we will be crimping the connector.

Step 2: Twist the stripper around the wire in clockwise direction 3-6times in one operation. Keep in mind that, depending on how the stripper is setup, you may need to spin the stripper more then 3 times. In any case, spin the stripper until the core has been reached and the jacket has been cut. Then remove the loose pieces of cut jacket, dielectric insulation, and shielding ground wire.

Step3: Fold the shielding ground wires back like pictured here. This will allow the wires to be pushed back when installing the connector. We do not want the shielding to make contact with the center conductor as this could cause a short at some point down the road. Also make sure the ground wire shielding is not cut through and falling apart.

Step 4: Insert the cable into the connector. Again making sure all the ground wires are pushed back. You will be able to see on the inside of the connector when the dielectric (white section in the picture) is flush with the inside of the connector. This is right where you want it to be. Make sure to twist connector as you put it on, as it will ensure the ground wires will make contact with the connector.

Step 5: Using the Crimp tool, crimp down the connector.
