This video shows you how to join two pieces of coaxial cable together or how repair a cut section or coax TV cable. You may want to do this if you need to make a coax cable longer or need to re-route a cable to a different place. The same process can be used to repair a coaxial cable that may have been accidentally cut, very common with gardening equipment. If you need to repair a coaxial cable join outside I recommend that you follow the instructions in this video as it will also show you the weatherproofing process.
This video shows how to join a coaxial cable via the F join. To do this you will need to install F connections on both ends of the coaxial cable. If you need a more detailed instructions on how install an F connection, please watch this video.
Tools You Will Need To Join A Coaxial Cable
1 x Coaxial cable stripping tool - Stanley blade or utility knife are fine.
1x Coaxial cable cutting tool - side cutters (even scissors will suffice)
Parts You Will Need To Join A Coaxial Cable
2x F Plugs
1x F Coupler (barrel connector)
Process For Joining or Repairing A Coaxial Cable
1. With the coaxial stripping tool or utility knife. Around 12mm or half an inch away from the cable end make a small round incision outermost layer (cable sheath) of the cable. Be careful not to cut out all the way though as you do not want to cut into the coaxial braid itself. Remove the cut cable sheath revealing the cable braid and screen.
2. Fold the cable braid back over the cable sheath.
3. If using a double screened cable, with the coaxial stripping tool cut away the cable screen and remove revealing the internal dielectric material.
4. With the utility knife, cut the dielectric material leaving around 3mm of insulation in place.
5. Screw the F plug into position over the top of the folded back cable braid. Keep twisting the until the dielectric is flush with the inside beginning of the threaded part of the plug. You should be left with 2mm of the centre conductor protruding the end of the plug. This is also known as "the stinger"
6. If you have any more than 2mm of the centre conductor protruding the end of the plug, trim back to 2mm using the cable cutting tool.
7. Repeat this process on the other side of the coaxial cable or other coaxial cable.
8. Screw the barrell connector/ F coupler into both F connectors and tighten.
You now have a professionally joined coaxial cable, if done correctly signal loss should be minimal and make no difference to your signal strength.
