Dipole and Inverted Vee Antenna Calculator. 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 .
5 cze 2021 · The Antenna Calculator for Half-Wave Dipoles. Enter your desired frequency (MHz) of operation (i.e. 3.55). If you have no particular preference within a given ham radio band, then simply enter its center frequency (i.e. 7.15 for the 40 meter band).
7 paź 2024 · Use this calculator to find the dimensions of a Dipole antenna [1] designed to operate at a specified wavelength or frequency. A half-wave dipole antenna is comprised of two quarter-wavelength conductors placed end to end.
Full Dipole Length: The calculator provides the total length of the dipole antenna in centimeters factoring in the velocity of propagation using the selected velocity factor, following the formula: (300 / Frequency) * Velocity Factor * 0.5 * 100 cm. Single Element Length: This result shows half of the full dipole length, indicating the length ...
Enter the desired operating frequency in megahertz to get a good starting length for a dipole in both feet and meters. The formula for calculating the approximate length of a dipole is: Dipole length in feet: 468 / frequency in MHz
4 sty 2020 · To calculate a different frequency, you can recalculate the length in feet use the formula “Length feet = 468/frequency in MHz”. Divide the answer by 2 and this will be the length for each element of the dipole. An online calculator can also be used to calculate the length of the dipole. Advertisements.
