Question 112

What weather condition might decrease range at microwave frequencies?

  1. High winds
  2. Low barometric pressure
  3. PrecipitationBonne réponse
  4. Colder temperatures

Explication

At microwave frequencies the wavelength approaches the size of raindrops and other precipitation, so rain, snow and hail absorb and scatter the signal and shorten the usable range. Wind, pressure and temperature by themselves do not attenuate the signal in the same way.
