 If you have a coaxial cable that has recently incurred damage, you may be wondering how to go about fixing it. Fortunately, with a few easily obtainable tools and a helpful guide at your disposal, repairing a faulty coaxial cable can be a very simple undertaking. Read on to learn the basics of coaxial cable repair.

Step 1 - Protect Yourself
Before attempting to fix your coaxial cable, you must first make sure that both ends of the cable have been safely disconnected from any devices. When troubleshooting electronics, safety should always be high atop your priority list, so take care not to skip this crucial step.
Step 2 - Check for Stretching
Stretching is a common issue with with coaxial cables, so before attempting any repairs, make sure that the cable is relatively close to the devices to which it is connected. If the cable is being stretched, the strain stands to impede the signal the cable is carrying. Additionally, make sure the cable is perfectly straight and that there are no bent or twisted areas. If you spot any, use your hands to firmly straighten them out.
Step 3 - Inspect the Connector Pins
Bent connector pins are another common cause of coaxial cable issues, so having safely disconnected your cable, your next step should be to carefully inspect the small metal pins found at the center of your cable's connectors. If these pins are not perfectly straight, use a pair of pliers to gently straighten them out. This should ensure that your cable's signal is able to flow smoothly and unimpeded. However, if the pins are unsturdy and strike you as excessively loose, you should look into replacing the cable.
Step 4 - Inspect the Outer Jacket
If faulty connectors aren't the source of your cable's problem, proceed to thoroughly inspect the cable's outer jacket for any tears. Should you come across any, apply electrical tape to the torn area of the jacket. Make sure the tear has been sufficiently patched before reconnecting the cable. Alternatively, you can patch rips and tears with liquid electrical tape, which, after drying, will essentially create a fresh protective coating over any damaged areas. This method works well in patching small rips and tears, but larger openings in your coaxial cable's outer jacket will oftentimes require you to replace the cable.
Step 5 - Inspect Your Connectors
If no rips can be found in your cable's outer jacket, the problem may stem from loose connectors. To confirm this, use your fingers to gently wiggle the connectors. If one or both of the cable's connectors appear to be loose, they will need to be replaced. To do this, cut the loose connectors off with the aid of your cable cutters. Once they have been successfully detached, simply twist on the replacement connectors in a counterclockwise fashion.
When repairing a coaxial cable, just remember these five easy steps and your cable with be up and running again in no time.
