RadioWORKS: A tool for calculating radio wave properties. Get frequency info, such as free-space wavelength, proper antenna lengths, band info, propagation methods, transmitter configurations, etc. Calculate path loss using Free-Space, Flat-Earth, Hata Urban, Hata Suburban, or Hata Open Area models. Predict how a proposed transmitter power change or range requirement change will affect existing system range or power output needs, respectively.
