Because it provides less signal loss, quad-shield coaxial cable is used for ___ TV signals.

Quad-shield coaxial cable is designed with multiple layers of shielding to reduce signal loss and improve resistance to interference. This makes it especially suitable for carrying digital TV signals, which require higher quality and integrity in transmission to ensure clear playback and minimize errors. Digital signals are more sensitive to noise and interference compared to analog signals. The improved shielding in quad-shield coaxial cables helps maintain the quality of digital signals over longer distances, making it a preferred choice for installations where preserving signal fidelity is critical.

In contrast, while analog signals can also be transmitted over coaxial cable, they are generally more forgiving of some level of signal degradation. Therefore, the advanced shielding capabilities of quad-shield coaxial cable are most beneficial for digital signals, ensuring that the data transmitted remains intact and that the viewer experiences high-quality reception.
