Which type of cable is most often used for television signal distribution in new residences?

The cable most commonly used for television signal distribution in new residences is 75-ohm RG6 coaxial cable. This type of cable is specifically designed to carry both video and audio signals, making it ideal for television, broadband internet, and other signals.

The 75-ohm impedance is optimal for minimizing signal loss over long distances, which is crucial for maintaining high-quality picture and sound. Furthermore, RG6 coaxial cable features better shielding compared to other types of cables, which helps protect against interference from external sources and ensures a more reliable signal transmission.

While other options may have specific uses—such as 50-ohm RG58 for radio frequency applications, Cat6 Ethernet for data networking, or 12/2 NM cable for electrical wiring—the RG6 coaxial cable is the recognized standard for distributing television signals in residential settings, making it the appropriate choice in this context.
