Computer Cable Store has created the following "How
to Terminate Coaxial Cable" to help you
do-it-yourself using
bulk coaxial cable. Within this DIY article we
have included everything you will need to find the
materials, tools, and info on how to build
coaxial patch cables.
We will discuss materials needed, cable preparation,
as well as connector termination.
Materials:
The first and most important material we will be
using is the cable. Bulk
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:
RG-59 Coaxial 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 so 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 since
been replaced by either RG-6 or RG-11. RG-59/U has
an impedence of 75 ohms.
RG-6 Coaxial 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. RG-6 in general has an
impedence of 75 ohms.

BNC Connector - Crimp - RG6 - Male - 2 piece
ComputerCableStore™ BNC Connectors will save you money by allowing you to assemble your own BNC Cables. BNC Connector - Crimp - RG6 - Male - 2 piece from ComputerCableStore™ for RG6 The BNC (Bayonet Neill Concelman) connector is a very common type of RF connector used for terminating coaxial cable. The BNC connector is used for RF signal connections, for analog and Serial Digital Interface video signals, amateur radio antenna connections, aviation electronics (avionics) and many other types of electronic test equipment. It is an alternative to the RCA connector when used for composite video on commercial video devices, although many consumer electronics devices with RCA jacks can be used with BNC-only commercial video equipment via a simple adapter. BNC connectors were commonly used on 10base2 thin Ethernet networks, both on cable interconnections and network cards, though these have largely been replaced by newer Ethernet devices whose wiring does not use coaxial cable. Some ARCNET networks use BNC-terminated coax.

Step 1: To begin, 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 want to test the stripper on a scrap
piece of cable first 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
two or three times. 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 your putting it on, as this will
ensure the ground wires will make contact with the
connector.
Step 5: Using the
Ideal Crimp Tool, with the correct die (see
materials), crimp down the connector. This specific
crimp tool prevents over crimping the connector with
a locking device that only allows crimping to a
determined level, insuring a perfect crimp. Be
aware, however, that other crimp tools may not have
this feature.
