How reliable is coaxial cable?

Coaxial cable is generally considered reliable for transmitting data, video, and audio signals over long distances due to its design, which minimizes interference and signal loss. Its protective layers shield the inner conductor from external electromagnetic interference, making it suitable for both residential and commercial applications. However, its performance can be affected by physical damage or poor connections, so proper installation and maintenance are essential for optimal reliability. Overall, when used correctly, coaxial cable can provide a stable and consistent signal.
