Groundwave Propagation
Groundwave propagation refers to the way radio waves travel along the Earth’s surface. Instead of going straight into the sky, these waves follow the contours of the ground, bending and diffracting over hills, buildings, and obstacles. This type of propagation is especially useful for transmitting signals over long distances at low frequencies, such as AM radio broadcasts. Groundwave signals can maintain strength over hundreds of miles, making them reliable for communication beyond the line of sight. The efficiency of groundwave propagation depends on factors like frequency, ground conductivity, and terrain.
