Space wave propagation is direct line of sight propagation between the transmitting and receiving antenna, typically occurring at frequencies above 30 MHz. Propagation could also occur by reflection from the ground to the receiving antenna, with attenuation. Space wave propagation occurs through the troposphere, the lowest layer of the earth&#8217;s [&hellip;]"}
