Coaxial cables are primarily used for which of the following?

Coaxial cables are primarily recognized for their effectiveness in transmitting television signals. The cable consists of a central conductor surrounded by insulation, a metallic shield, and an outer cover, which allows it to carry high-frequency signals with minimal interference. This design is particularly suitable for delivering cable television services, as it can handle the bandwidth required for multiple channels and high-definition content.

While coaxial cables can be used in other applications, such as internet connections and data transmission in some setups, their historical and widespread implementation has been in the broadcasting of TV signals, making this the most fitting choice.
