LORAN C (Long Range Navigation) signals propagate best over salt water surfaces due to the conductive properties of seawater. The presence of a large body of saltwater allows the radio waves to travel further because saltwater is a better conductor of electromagnetic waves compared to other surfaces. As a result, the signals can reflect off the surface of the water, enhancing their range and allowing for clearer reception at greater distances.

In contrast, rocky terrain, forests, and desert land do not provide the same conductive environment as saltwater. These surfaces can absorb or scatter the radio waves more, leading to a reduction in signal strength and range. Therefore, saltwater is recognized as the optimal medium for LORAN C signal transmission and reception.
