Use a Coaxial Cable Stripping Tool
It’s not impossible to strip a coaxial cable with a utility knife, but it’s not easy. A $15 stripping tool gives you fast and perfect results every time. Coaxial cable strippers have two blades: One blade cuts through the jacket without damaging the braid, and the other blade cuts through everything except the center conductor. Some pros prefer to leave the center conductor a bit long and trim it down (about 1/8 in. past the connector) after the connector is crimped on.
Use Coaxial Cable Compression Connectors
Buy coaxial cable connectors that can handle the highest frequency available. Some cheap coaxial cable connectors may work for a security camera, but not a Hi-Def TV or Internet signal. The same goes for wall plates. Not all wall plates have built-in coaxial cable connectors capable of handling high-end signals. When in doubt, buy the connector with the highest frequency rating. The rating should be displayed on the packaging.
Bond Coaxial Cable
Even if your Hi-Def TV is working fine, you might want to check to see that the coaxial cable is “bonded” to the house’s grounding system. Bonding simply means connecting two things to ensure electrical continuity and conductivity. In a home, it’s important that the electrical system, communication systems, metal plumbing pipes, metal gas piping and other metallic systems be electrically bonded together.
Electrically bonding various systems together limits the different voltage potential (pressure) and shock hazards that could be present during a lightning strike or other electrical anomaly. A difference in voltage potential can create strong currents that can jump between two different systems through an undesirable path, and that path could be you!.
The simplest way to bond your coaxial cable to the rest of the house is to run the cables through a grounding block, and then run a wire from the block to the grounding electrode (ground rod) or other qualifying grounding connection point. If you have no idea where any part of the home’s grounding system is, call an electrician. In addition to electrocution, improperly grounded cables could lead to damaged electronics and house fires.
