How to Replace an External Cable TV Line After It Is Cut

By Dan Harkins

The coaxial cable snaking around your home is probably being used to deliver cable or satellite programming to your televisions. Just one cut along the route can disable your entertainment completely and may require a costly visit from a repairman. However, if you've located where the coaxial cut is -- either outside or inside your home -- you can fix it yourself and avoid the out-of-pocket expense.

Things You'll Need

  • Replacement coaxial cable, if needed
  • Coaxial connectors (one male, one female)
  • Wire strippers
  • Silicon grease

Step 1

Remove the sheathing from one inch of each end of cut wire using wire strippers. Isolate the single copper wire inside by removing the outer plastic coating, the insulation (usually white) and the braided copper shield.

Step 2

Apply a thin coating of silicone grease to each end of remaining tubing, just shy of the copper wires to be connected (this waterproofs the new connectors).

Step 3

Slide one copper wire end through the male portion of the coaxial connector and firmly twist the connector onto the wire tubing. Snip the wire at the point at which it begins to extend from your connector.

Step 4

Cut your other copper-wire end to about half an inch long and slide it into the female connector. Twist the connector onto the tubing firmly.

Step 5

Screw the male and female connectors together and test your cable.
