The VHF (Very High Frequency) range is 30 MHz to 300 MHz. Use this calculator to find the dimensions of a Dipole antenna designed to operate at this frequency range.
A half-wave dipole antenna is comprised of two quarter-wavelength conductors placed end to end .
This calculator gives the length of a half wave dipole antenna. Enter the Frequency and the tool will compute the antenna length (L).
At a frequency of operation 200 MHz. The dipole length (L) is 28.1 inches or 0.71 meters.
The total length (L) of the dipole antenna is calculated as:
L = 468 / f
where f is the frequency in MHz.
f is calculated from the wavelength.
The length of each arm of the dipole
l = L/2
