Avoid Coaxial Cable Stingers
Once coaxial cable has been stripped, leave the foil in place, but peel back the braid. Make certain that not even one of the tiny wires of the braid touches the center conductor. That’s what the pros call a “stinger,” and stingers are notorious for wreaking havoc with signal quality.
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.
