If you need to splice a coaxial cable, you will need to purchase some specialized tools and minor components.
We can easily find these at your local electronics or hardware store.
Step 1 – Determine what type of cable you have
The most common cables for home use are RG6 and RG59. It marked the type of cable on the cable.
If you can’t find any markings to show the type of cable, you can measure it. RG6 is approximately 274 inches in diameter and RG59 is approximately 233 inches.
A simpler solution might be to cut out a piece and take it with you when purchasing your components.
Step 2 – Strip the wire
It is important to use a coaxial cable stripper to strip the coaxial cable, exposing about a half inch.
The stripping tool will accommodate different sizes of coaxial cable and will have an adapter to accommodate your type of cable.
Coaxial cables are not the same electrical cables and I build the coaxial cable stripper to accommodate and strip the cable layers without cutting or damaging the innermost copper cable, which will eventually protrude to mate with the female coupler.
When you have completed the stripping, you will have a wire with exposed white insulation covered by a wire mesh jacket with a protruding copper wire.
Fold the mesh jacket back over the outer wire jacket so that the insulation is bare. Your cable is now ready for the connector.
Step 3 – Install the compression connector
Slide the compression connector over the wire, being careful not to damage the protruding copper wire.
The central copper wire should protrude slightly past the end of the connector.
Step 4: fit and employed your compression tool
For this step, a specialized tool firmly set the compression connector on the ends of your coaxial cables.
Your compression tool will have adapters for your cable type.
You will can use for RG6 and RG59 coaxial type connectors, as well as other non-coaxial compression connectors.
Insert the cable with the loosely mounted connector into the compression tool where shower and squeeze the handle to connect the connector to the cable.
Step 5 – Repeat the steps
Repeat steps 1 through 3 for the other wire you need to splice.
Step 6: connect the two cables
Now connect each wire to the barrel connector. You will notice that your barrel connector will have a female connection port on both sides that the copper wire of the two cables will seat into. Tighten the cable connector collar onto the barrel connector on each side. Your splice is now complete.
If you are splicing the cable in order to extend your cable, you will need to purchase accessories to prepare four cable ends. Note that any additional cables that are spliced must be of the same type, either RG6 or RG59. Also note that this type of cable connector, once properly assembled, will make the connection weather resistant and suitable for outdoor use as required.
