NettetFor example, in lower short wave, which is around 300 kHz to 3 MHz, the radio propagation or radio wave can actually curve itself around the horizon or the curvature of the Earth. In higher short wave, which is what people in the 40s and 50s used to listen to when they wanted to hear international broadcasts, the properties are different again.
