The typical range of frequencies for cable services is from 5 MHz to 1 GHz. This frequency range encompasses the necessary bandwidth for various cable services, including analog television, digital television, and data transmission.

In the context of cable TV, the lower end of the spectrum (5 MHz) is generally used for upstream communication, such as customer interactions with the service provider, while the upper range (up to 1 GHz) accommodates downstream signals, which include all the channels and services provided to customers. This frequency allocation allows cable operators to provide a wide variety of services simultaneously over the same network.

To put this into perspective, while the options highlighting ranges outside of 5 MHz to 1 GHz might seem plausible in a broader telecommunication context, they do not accurately reflect the specific frequency bands used for cable TV services. For instance, a range extending to 10 GHz or between 10 MHz and 500 MHz would include frequencies relevant for different applications (like satellite communications or other wireless services), but they would not specifically represent the operational range for standard cable services.
