What is RG-6/U commonly used as?

Coaxial cable
Ethernet connector plug type
Telephone connector plug type
Fiber optics cable

The correct answer is: Coaxial cable

RG-6/U is commonly known as a type of coaxial cable, which is widely used for a variety of applications including cable television, satellite television, and internet connections. This type of cable is designed to carry high-frequency signals with minimal interference, making it suitable for delivering high-quality video and data transmissions over longer distances compared to other types of cables. The construction of RG-6/U, which includes a thicker solid copper or copper-clad steel core, insulation, and a shield, enables it to effectively minimize signal loss and maintain signal integrity, essential for the reliable transmission of audio and visual content. This attributes to its prevalence in residential and commercial installations where dependable connectivity is paramount. The other options, which include different types of connectors and cables, do not pertain to RG-6/U, thus reinforcing that RG-6/U is specifically a coaxial cable.
