Antenna & Wave PropagationDipole Antennas

Ignoring practical shortening effects, the approximate total length of a half-wave dipole for 300 MHz is?

  • A0.25 m
  • B0.5 m
  • C1 m
  • D1.5 m
Report an error
Correct Answer: B. 0.5 m
Explanation: At 300 MHz lambda≈1 m, so a half-wave dipole is approximately lambda/2=0.5 m.
Reference: Standard antenna and wave propagation: dipole antennas
