Which RG cable type is typically used for short distance applications such as composite video?

The RG-59 cable type is most commonly used for short-distance applications, particularly for composite video. This type of coaxial cable is designed to handle video signals effectively over moderate distances, making it suitable for devices like surveillance cameras and older video equipment where high-frequency signal loss is less of a concern.

RG-59 has a smaller diameter and lower signal loss compared to other coaxial cables, allowing it to transmit standard video frequencies without significant degradation. This characteristic is particularly beneficial in setups that involve connections between devices over short distances, where the signal remains strong and clear.

In contrast, other RG cable types, such as RG-6 and RG-11, are typically used for longer distances, especially in applications requiring more bandwidth, such as broadband internet and cable television—where minimizing signal loss over longer runs is crucial. RG-7 is less commonly used in typical consumer applications and does not have a specific advantage for short video applications.
