How Far Can RF Signal Travel?

How Far Can RF Signal Travel? Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). What determines RF range? Radio waves at lower frequencies propagate further than radio waves at higher frequencies. For example, a 900 MHz
