Here’s what to do when you’ve accidentally cut an RG6 or RG59 coaxial TV cable in your roof or wall. This how to guide will show you how to join the cable so that your Digital TV will work again.
This procedure is mainly aimed at installed coaxial cables. If you accidentally cut or break a fly lead that goes from the wall to the back of your TV it’s best to replace it.
The end result is a cable that works nearly as well as if you hadn’t broken it in the first place. You will have some loss of signal from the connectors and joiner, but it’s much better than doing any other kind of joint without the proper connectors and joiner.
Parts and Tools
To do this, you’ll need to the following parts(links go to RG6 parts, but if using RG59 cable, change your search appropriately):
- F type female joiner (eBay link for F Type female joiners)
- RG6/RG59 Compression F Connectors or RG6/RG59 Crimp F Connectors
You’ll also need these tools:
- Large side cutters (eBay link for 4.5″ side cutters)
- Rotary coaxial stripper (eBay link for rotary strippers)
- Compression tool (eBay link for compression tools) or Hex crimper (eBay link for hex crimpers)
- Try to pull some slack cable so you have at least 10 centimetres of overlap. If the cable is tight it can be hard to do the terminations(putting ends on the cable) and joint the cable.
- Cut the damaged ends off the cable with a pair of cutters. This will give you a clean cut end to work with.
- Strip the two cable ends with a rotary stripper. You can also strip the cable with a pair of cutters, but it’s harder.
- Terminate the cables with F connectors. You can use crimp or compression F connectors, but I recommend compression. Twist-on F connectors are also available, but I don’t recommend them.
- Screw both ends of the cable into either end of an F to F female adaptor(find them on eBay by searching F-type female joiner). They need to be firmly finger tight. It doesn’t matter which way around you put the two ends in.
