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.
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.

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.
This page contains tables showing usable feedling lengths (LF) for 3 different sizes (LD) of antennas. It also shows lengths for generic 600 Ohm line and 450 [400] Ohm Wirmean line. IMPORTANT: ANTENNA MATCHBOX SPECIFICATIONS:
The antenna length chart, which is the subject of this article, arose out of the need to have a convenient and ready ref erence, other than a weighty handbook, for measuring antenna lengths.
1 wrz 2021 · This chart serves as an aid in trimming the length of HF antennas. The chart estimates, over the length of an approximate quarter wavelength, the required change in length to shift the fundamental antenna resonance by a specific amount of kHz.
