Source sentences:
text: The radiation pattern of a straight random wire antenna is unpredictable and depends on its electrical length; its length measured in wavelengths (λ) of the radio waves used.
text: The length is not critical, typically from one to two wavelengths (λ) end-to-end, but for any given length and frequency, there is an optimum acute angle at which the sections should meet.
text: radiating element that is from 1/20th wavelength (λ) to 1/4 wavelength above the ground.
