A commonly used type of coaxial cable used for video applications is ___.

In this context, coaxial cables are categorized by their RG (Radio Guide) designations, and several types are indeed used for video applications. Each type offers specific benefits depending on the application, such as signal loss, bandwidth, and distance capabilities.

RG59/U is commonly used for standard-definition video signals and is known for its flexibility and suitability for short runs. It generally has a smaller diameter and is often chosen for applications like CCTV systems and connecting antennas to a television.

RG6/U is more prevalent for high-definition video applications. This type features better shielding and lower attenuation, which is essential for maintaining signal quality over longer distances. RG6 is typically used in residential and commercial settings for cable television, satellite, and broadband internet.

RG11/U is less common for residential use but can be employed in specific scenarios where longer distances are involved, as it has even lower signal loss compared to RG6. It is primarily used in professional and commercial applications.

Since all these types of coaxial cables—RG59/U, RG6/U, and RG11/U—can be utilized for video applications, the correct answer reflects that they all belong to the category of coaxial cables suitable for video transmission. This choice acknowledges the versatility and applicability of each type
