In home run CATV (Community Antenna Television) systems, the type of signal used is radio frequency (RF) signals. RF signals are ideal for CATV systems because they can carry multiple channels and are suitable for transmitting over coaxial cables commonly used in these setups.

Understanding the nature of RF signals is crucial—they operate within a specific frequency range and are particularly effective at maintaining quality over distance, which is important for ensuring that the signal delivered to television sets is clear and reliable. This makes RF the primary signal type transported in such systems.

While digital signals have become prevalent in various types of broadcasting and data transmission, CATV systems specifically rely on RF signals as the standard for channel transmission, whether those channels carry analog or digital content. Mixed signals refer to a combination of different signal types, which isn't typical for the dedicated channel delivery characteristic of a home run CATV system.
