Radio Works

RadioWORKS is a tool for calculating various items related to radio waves and radio wave propagation. Get detailed information about a frequency, such as the free-space wavelength, proper antenna lengths for common wavelength ratios, band classification, propagation methods, common transmitter configurations, etc. Calculate path loss using the Free-Space, Flat-Earth, Hata Urban, Hata Suburban, or Hata Open Area mathematical models. Use the Distance and Power change prediction calculator to predict how a proposed transmitter power change, whether an increase or a decrease, will affect your usable range -- OR -- how a proposed range requirement change, whether an increase or a decrease, will affect your transmitter power requirements, while factoring in the signal decay rate observed in your current system. Additionally, all mathematical formulas used by the application are on display, including explanations and usage information.

Antenna Maker

Different antenna design prrograms in one zipped program.

Moxon Antenna

MoxGen will show you the dimensions and (optionally) generate an antenna model file for a 50 ohm Moxon Rectangle antenna, given the design frequency and wire size.  The program is based on an algorithm developed by L. B. Cebik, W4RNL.

HFProp

HFProp can display daily propagation charts showing the best time of day for communication with a particular location. These charts are based on the same simple algorithms that are used for the map display. Again, they are intended to illustrate how propagation over a particular path changes during the course of the day. They should not be expected to provide an accurate prediction of when it will be possible.
