Which of the following is a common use of coaxial cable?

Coaxial cable is commonly used to carry RF signals between a radio and an antenna due to its specific design, which helps minimize signal loss and interference. The structure of coaxial cable, consisting of an inner conductor surrounded by a dielectric insulating material and an outer conductive shield, creates a controlled transmission environment that is particularly effective for radio frequency (RF) applications. This shielding protects the signals from external electromagnetic interference, which is crucial in maintaining the integrity of the signal over distance.

In contrast, other options list uses that are not typical for coaxial cable. For example, while DC power might be carried through wiring, it is usually done with separate types of wire rather than coaxial cable. Additionally, securing masts and tubing involves mechanical fasteners and supports rather than electrical conductors. Finally, while coaxial cable can be used for some types of data transmission, connecting data signals from a Terminal Node Controller (TNC) to a computer typically involves other types of cables like serial cables or USB connections rather than coaxial.
