Waveguide (radio frequency)
In radio-frequency engineering and communications engineering, waveguide is a hollow metal pipe used to carry radio waves. Prior to the 1920s, practical work on radio waves concentrated on the low frequency end of the radio spectrum, as these frequencies were better for long-range wikipedia.org
