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.

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.
5 cze 2021 · The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole. The results are conveniently displayed in inches, centimeters, feet and meters. This formula to obtain the length of a half-wave dipole antenna will give a good ballpark value to start with.
30 lip 2024 · Dividing 468 by the antenna frequency will give you the length of the antenna in feet. Once you have the entire length, you can divide it by two and obtain the length of each arm of the dipole antenna.
23 sty 2024 · For each band, I will provide a typical wire length for one side of a dipole for the target frequency, which is usually the bottom edge of the band, along with expected variance, recommended starting wire length, expected SWR bandwidths, length of the hanging tails, and an estimate of the change in wire length to shift the frequency by 100 kHz ...
Sufficiently accurate for wire antennas up to 30 Mhz. The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and inches or 143/freq-in-Mhz for meters .
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.
