Question 377

What is the approximate length of the driven element of a Yagi antenna?

  1. 1/4 wavelength
  2. 1/2 wavelengthBonne réponse
  3. 3/4 wavelength
  4. 1 wavelength

Explication

The driven element of a Yagi is a resonant dipole, so it is approximately a half wavelength long; the parasitic elements are then made slightly longer or shorter than it.
