Satellite coaxial cable provides the path of signal transmission between the satellite dish and receiver box. A healthy cable has no rips or exposed areas of wire. If you have a damaged cable, you'll see signs of interference or experience loss of service. Check for loose points of connection along the cable and evidence of corrosion at the dish, receiver and multiswitch if applicable. If you see a damaged segment or connection, you may find it easier to replace that part rather than replacing the entire length of cable.

Disconnect the corroded connector from its source. Cut the cable approximately an inch behind the connector. If the cable itself is damaged, cut out the damaged section and an extra inch on each side of the cable where the damage occurred.

Prepare the cut ends of the coaxial cable, using the coaxial cable strippers. If you use a knife, strip back a 1/4-inch length of cable coating to expose the copper core. Carefully strip another 1/4-inch length, taking off only the outer coating and leaving the steel braid intact.

Peel back the steel braiding and push an F-connector onto each prepared end of cable. Ensure that the white core is flush with the inside of the F-connector.

Attach the new connector to its source and wrap it in silicone tape to prevent future corrosion if the original problem was a corroded connection. If the problem was a damaged line, connect both prepared ends of cable to a female to female F-splice adaptor. Wrap it in silicone tape to weatherproof your new connection.
