short wave
Global radio band
Short wave refers to radio waves with wavelengths roughly between 10 and 100 meters, capable of traveling long distances by bouncing off the ionosphere.
Short-wave radio historically enabled international broadcasting and amateur communication across continents: My grandfather listened to the BBC on short wave.
Also spelled shortwave.
