Formula & Theory
λ = 300 / f(MHz), Electrical Length = (L ÷ λ) × 360°This formula is used to calculate antenna parameters for wavelength calculator.
Overview
Wavelength Calculator provides calculator-specific guidance for the displayed engineering inputs and result.
Input Guide
Enter Frequency, Physical Length, Velocity Factor exactly in the units shown by this wavelength. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.
- Frequency — use MHz.
- Physical Length — use m.
- Velocity Factor.
Output Guide
The results describe the calculated wavelength values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.
How This Calculator Works
The Wavelength uses λ = 300 / f(MHz), Electrical Length = (L ÷ λ) × 360°. Supply Frequency (MHz), Physical Length (m), Velocity Factor in the displayed units, then use the calculated values as the first engineering target for this wavelength & frequency design or analysis.
Design Notes
Actual results depend on installation, materials, losses, tolerances, and operating conditions.
Build and Tuning Notes
Validate the calculated target with measurement or simulation before finalising the system.
