# RF wavelength and antenna length
# Scope: Free-space wavelength and quarter-wave physical length.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

frequency = 2400000000 Hz
lightSpeed = 299792458 m/s

wavelength := lightSpeed/frequency [mm]
quarterWave := wavelength/4 [mm]

check quarter wave envelope: quarterWave <= 40 mm

scenario alternative: frequency = 1.92e+09 Hz
