Lengthening Antennas
Electrical lengthening is the modification of an aerial which is shorter than a whole-number multiple of a quarter of the radiated wavelength, by means of a suitable electronic device, without changing the physical length of the aerial, in such a way that it corresponds electrically to the next whole-number multiple of a quarter of the used wavelength. A lengthening is only possible to the next whole-number multiple of a quarter of the radiated wavelength. Thus an aerial with a length corresponding to the eighth of the radiated wavelength can be extended only to a quarter-wave radiator, but not to a half wave radiator.

Famous quotes containing the word lengthening:
“We mothers are learning to mark our mothering success by our daughters’ lengthening flight. When they need us, we are fiercely there. But we do not need them to need us—or to become us.”
—Letty Cottin Pogrebin (20th century)
