What type of connector is used to connect coaxial cables?

The correct choice for connecting coaxial cables is the BNC connector.

BNC connectors are widely used in various applications, including television, radio, and telecommunications, due to their reliable performance and ease of use. They enable quick connections and disconnections while maintaining strong signal integrity, which is crucial for coaxial cable applications. BNC connectors are designed to fit snugly onto the circular shape of coaxial cables, providing an effective electrical connection that minimizes signal loss.

While other connectors, such as N and F connectors, are also used with coaxial cables in specific contexts, BNC connectors are especially prevalent in broadcast and video applications. N connectors are typically used for higher frequency applications, like in RF telecommunications, where their larger size accommodates higher power and reduces signal loss. F connectors are commonly used in cable television and Internet connections but are optimized for different cable types and requirements.

RCA connectors, although they can handle video and audio signals, are not ideal for professional coaxial connections as they are designed more for unbalanced audio and video applications rather than the balanced coaxial style. Thus, the BNC connector stands out as the most appropriate choice for general coaxial cable connections.
