What is the approximate length for a 1/2 wave dipole antenna cut for 3.550 MHz?

  1. 42 feet
  2. 84 feet
  3. 132 feetRespuesta correcta
  4. 263 feet

Explicación

Applying 468/f gives 468/3.550 = 131.8 feet, which rounds to 132 feet. The 263 foot choice is close to a full wavelength at this frequency (936/3.550 = 264 feet), not a half wave.
