Having a wavelength of approximately 10 to 200 meters.
Capable of receiving or transmitting at wavelengths of approximately 10 to 200 meters.
A shortwave radio.
An electromagnetic wave that is shorter than those used in commercial broadcasting, usually a radio wave 60 meters or less in length.
A radio or radio band for broadcasting or receiving shortwaves.
A radio wave with a frequency between 5.9 megahertz and 26.1 megahertz. Shortwaves broadcast from the Earth's surface are reflected by the upper atmosphere and can travel great distances around the planet. The shortwave band of the electromagnetic spectrum is used for amateur radio communications.
Referring to the short wavelength of high frequency (HF) radio, which is in the frequency range of 3
Any shortwave frequency, having a wavelength between approximately 10 and 200 meters.
Many stations broadcast on shortwaves.
Any wave in the shortwave frequency band.
Shortwaves are longer than microwaves.
