7 paź 2024 · In this post we provide a calculator that gives the length of an antenna that can be used in the Frequency Modulation (FM) Band.
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.
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.
Antenna Length Calculator. *ALK = Antenna Length Constant. Includes calculated K and end-effect factors. 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.
The formula λ = v/f is used to calculate the effective length of an antenna. In this formula, the Greek lowercase letter lambda (λ) represents the wavelength, ‘v’ represents the velocity of the wave propagation, and ‘f’ represents the frequency at which the antenna will operate.
Enter the formula for the antenna calculation (normally 234/f): divided by Freq. MHZ. The vertical length is feet. The 4 radials are each feet.
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.
