Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference. It is primarily used by cable TV companies to connect their satellite antenna facilities to customer homes and businesses.

A coaxial cable, also known as a coax cable, is a specialized cable used to send data and radio frequencies without extra electrical interference, known as static. They're commonly used for devices like TVs, the internet, and radios.
-
If you wish to watch a live TV service through your TV like Freeview or Freesat you will need a coaxial cable connecting into your TV. If you have a TV aerial socket plate or satellite socket a coaxial flylead will be required to connect between this and your TV.
-
Connect one end of the coaxial cable to the cable wall outlet, then connect the other end to the modem. Connect the modem power cord into an electrical outlet, then connect the other end to the modem.
-
Poor quality coaxial cable can impact TV reception, so it's important to choose the best cable for the job. Coaxial cable designed for domestic television should be 75 Ohm, with RG-6 coaxial being ideal for TV.
-
Coaxial cables generally use the label “RG,” which stands for “Radio Guide” and is accompanied by numbers to create a code that distinguishes the cable model. Once you find the designation code, you will quickly identify the type of coaxial cable!
-
Does Length of Coaxial Cable Affect Signal Loss? Yes, the greater the length of the coax cable you use, the more signal loss you will experience.
-
The RG11 cable will give you a better signal at its end compared to the end of the RG6 when given a specific length of cable. Meanwhile, noticeable attenuation will only happen to the RG11 cable once you start using longer RG11 cables since the signal travels longer distances, leading to attenuation.
-
RG-59 coaxial cable is the best type for CCTV systems, but RG-6 can also be used. RG-6 can run longer distances than RG-59 without loss to a video signal, however, it's a thicker, firmer cable that isn't as convenient to work with.
-
The three most commonly used coaxial cable types for video applications are RG59/U, RG6/U, and RG11/U. RG59/U is available with either solid copper or copper-clad steel center conductor. It's suitable for basic analog TV antenna feeds in residential applications and for basic CCTV systems over short cable runs.

Compared to ethernet cables, coax cables are better at transmission speeds and frequencies.
