RF Wavelength Calculator
Calculate wavelength and quarter/half-wave lengths from frequency.
Processing stays in your browser. Uses the speed of light with your velocity factor. Actual antenna dimensions also depend on geometry, materials, loading, and tuning.
How to use the rf wavelength calculator
Calculate wavelength and quarter/half-wave lengths from frequency. Complete the frequency (mhz), velocity factor (0.01–1) fields above. Choose Run tool, review the output, then copy or download the result.
Example
100 MHz in free space has a wavelength about 3 metres.
