Coaxial Cable

Coaxial Cable

Coax, short for coaxial, is a type of cable used to transmit data, the internet, video and voice communications. A coax cable is made up of an aluminum and copper shield with an outer plastic jacket (see below) with the dielectric insulator helping to minimize signal loss. Do you need a coax cable for internet? If you have cable internet, then yes, you do need a coax (or coaxial) cable to connect to the internet. Your internet provider should give you one with your modem, but if you're missing one, you can find them for pretty cheap on Amazon.

A Smart TV only needs a coaxial cable if you want the TV to receive and display signals that arrive at the TV by coaxial cable. There are other ways to receive signals, primarily via WiFi and by direct connection to a playback device. Cable internet service uses the same coaxial cable network as cable television to provide your home with internet. First, your internet service provider sends a data signal through the coaxial cable, or coax cable, into your home—specifically, to your modem.
