A Step-by-step Guide for crimping RG59 or RG6 Cables to a BNC connector.
This tutorial shows how to connct bulk RG59 and RG6 coaxial cables to BNC, F-type, or RCA connectors.
You can connect or extend your own cables for Cable or Satellite TV, and other video applications. RG59 is typically fitted with
F-Pin ends (for Cable TV) or BNC ends (professional video applications). RG59 cable
can also be used to connect to RCA connectors.
Step 1: Identifying the Cable
|Some RG59 and RG6 cables comes paired with a
power cable. If this is the case, the power cable is easily identified by
its dual cable structure (pictured as the red and white jacketed cable
above). This distinguishes the upper cable as your A/V cable.
||Separate the power cable from the A/V cable
simply by pulling the two apart. If you have trouble splitting them, use a
cutter and make a small incision between the cables to assist the
||Now that you have your isolated coaxial cable,
you are ready to go on to the next step.|
Step 2: Making a Clean Cut
|After you have identified your Video Cable, you
will need a Cable
Cutter. Make sure the cutter is sharp and in good condition to
avoid any unclean cuts.
||Make a clean cut at the tip of your cable with
your Cable Cutter. Do not cut too far back from the tip to avoid a loss of
length of your cable.
||Making a clean cut on your cable will ensure a
snug fit and an accurate positioning of your cable into the
Step 3: Setting the Stripper
|Next you will need a wire
stripper, which will expose the interior layers of the cable. This
will allow you to gain access to the conductor and also to remove the
shielding beneath the surface of the cable.
||Make sure that your setting on the wire
stripper matches the desired length you want the wire to be stripped. The
red arrow in the picture shows the position of
the setting. Simply pop out the orange X and insert it back into position
to the desired setting, matching the number with the black arrow on the
stripper itself. The number key on the left hand side shows the length
each setting will yield.|
Step 4: Stripping the Cable
|Now that you have set your stripper, it is time
to put your wire into the stripper. Make sure that you put your stripper
on the correct way. The end of the wire should match up with the end of
the stripper. Make sure that the two are on the same plane before
||To strip the wire, simply rotate your stripper
around the cable either clockwise or counter-clockwise. A couple rotations
is sufficient until you feel little to no resistance. Do not over strip
your cable in case of damaging the conductor. Also make sure that you
strip enough so that you expose all the parts desired.
||Simply remove your stripper and the portions of
the cables that have been cut. Your cable should look something like the
above picture. Three identifiable layers should be present: the Cable
jacket, the mesh shielding and the conductor. |
Step 5: Crimping part 1 precise
|Slide the metal cylinder from the BNC-59 kit
onto the BNC cable.
||Slide the gold cap onto the center conductor.
Make sure that no shielding wires are touching the center conductor or the
gold cap. Trim the center conductor so that the gold cap will fit over the
||Crimp the gold cap.|
Step 6: Crimping Part 2
|Slide the BNC connector onto the cable. The
aluminum foil and center should be inside the BNC cap, the jacket and the
shielding wires may be outside.
||As the BNC connector is slid onto the cable,
the golden cap should line up close to the end of the connector.
||In order to cap the BNC connector with the
metal cylinder, trim the outer jacket as needed. Slide the metal cylinder
to the BNC connector.|
Step 7: Crimping part 3
|Crimp the metal cylinder to the BNC connector.
||The finished cable should look something like
