M Metres in Inches ft Feet A. The 4 radials are each feet. This frequency to wavelength calculator is especially useful for the calculation of the element length of the dipole antennas.
To use the calculator enter the desired operating frequency in megahertz to get a starting length in both feet and meters for building a quarter-wave.
Often a formula for the length of a dipole in feet is seen as 468 frequency. L 468 f Where L is the length feet. Dipole length in feet. The larger the wire the wider the bandwidth.
