High score: Can you use a network cable instead of a cable TV signal line? Where are the wires?

I think so, too. It's all communication.

The middle of the cable TV feeder is a hollow plastic partition, which reduces the signal interference between the cable and the center line, while the cable is a twisted pair, and the cable passes a high-frequency signal of >: 10MHz. At this time, the insulated wire between the wires is equivalent to a dielectric plate, and the capacitor formed by it and the wires plays a role in bypassing and attenuating the high-frequency signal (the signal phase is delayed), which is different from the TV feeder.

So it will affect the TV signal.

The same is true of wires.

However, short-distance connection is feasible.
