Ham Radio HF/VHF Antenna Lengths Chart. Here is a handy chart for determing 1/4 wave verticals, 1/2 wave dipoles, and full wave loop lengths. All antenna lengths in the information below are in feet and are the results based on the standard formula of 468 / FMhz = total length in feet.
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.
2.1. Antenna length based on the following formulars: 1/2 λ dipole (feet)= 468 / frequency in Mhz. 1/2 λ dipole (meters) = 142.65 / frequency in Mhz. Full wave loop (feet) = 1005 / frequency in Mhz. Full wave loop (meters) = 306.32 / frequency in Mhz. Cut wire slightly longer for connecting insulators and pruning. 22-Jun-2007 09:30 AM.

This calculator is an aid for determining antenna element lengths, based on Frequency, Type (Wire or Tubing), and Diameter (AWG#, inches, mm) of the element. At the top of the calculator, enter the Frequency (1 to 30 MHz) of interest.
NOTE: 1. If using a spring, deduct. the length of the spring from the overall whip length as shown above. 2. If using a black coated whip, for proper electrical contact with the antenna, remove the black coating from the portion of the whip which goes into the antenna ferrule (cone).
30 lip 2024 · Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
