What is a characteristic feature of a ground screen system?

The characteristic feature of a ground screen system that makes it notable is its use of multiple conductive wires that are laid on the ground. This configuration serves both as an effective means to improve grounding efficiency and as a method to facilitate electromagnetic wave propagation.

The conductive wires in a ground screen system are arranged in a specific pattern that maximizes the surface area in contact with the ground, thereby enhancing the grounding system’s ability to dissipate energy and reduce potential differences in the system. This is crucial in applications involving radio frequency (RF) systems, as it helps prevent interruptions and disturbances from external sources, while optimizing the performance of antennas.

While radially spaced ground rods are indeed another type of grounding mechanism, they do not specifically define a ground screen system. The option regarding installation above ground does not apply, as ground screens are inherently positioned on the ground. Lastly, although ground screens can help mitigate issues caused by electromagnetic interference, their primary defining characteristic is the arrangement and application of conductive wires on the ground.
