Approximately how long is a Yagi’s driven element?
234 divided by frequency in MHz
1005 divided by frequency in MHz
1/4 wavelength
1/2 wavelength✓الإجابة الصحيحة
الشرح
The driven element of a Yagi is a resonant dipole, so it is about a half wavelength long, with parasitic elements set slightly longer or shorter than that. The quarter-wave and full-wave formulas offered describe other element lengths entirely.
