30 lip 2024 · To calculate the length of an antenna, you may use the formula: L = 468 / f. l = L /2. where: L — Length of the dipole antenna; l — Length of each arm of the dipole; and; f — Frequency. Dividing 468 by the antenna frequency will give you the length of the antenna in feet.
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.
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.
7 paź 2024 · Formula. The total length (L) of the dipole antenna in feet is calculated as: L = 468 / f. where f is the frequency in MHz. A dipole antenna is comprised of two arms of equal length. l = L/2. How to Calculate the Dipole Length. Enter the antenna’s frequency of operation with the appropriate units Hz/kHz/MHz/GHz.
5 cze 2021 · The most widely used formula to calculate the approximate overall length of wire required for a dipole is: 468 / frequency (MHz) = length of wire in feet. The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole.
