3 paź 2024 · To determine the ideal length of an EFHW antenna for a specific operating frequency, you can use the formula: \[ \text{Antenna Length (m)} = \frac{468}{\text{Frequency (MHz)}} \] This formula gives the approximate total length in meters of the half-wave wire antenna.
19 sty 2017 · I want to use an end-fed wire antenna, but what would be the best length of wire for the 20m and 40m bands? Is there a way to work this out? This is assuming a tuner will be used.
15 sie 2023 · To calculate the length of an end-fed antenna, you can use the formula: Antenna Length (in meters) = Speed of Light (m/s) / Frequency (Hz) / 2. How long should an end-fed wire be? The length of an end-fed wire antenna depends on the frequency it’s intended for.
15 lip 2024 · Using the EFHW Antenna Calculator is straightforward: Input Frequency (MHz): Enter the operating frequency of your radio equipment in megahertz (MHz). Calculate Length: Click the “Calculate Length” button to determine the recommended length of the EFHW antenna.
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.
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.
