Radio Propagation Calculator

1.3

A radio frequency calculator that can determine the transmission path between the receiver and the signal source based on user-defined parameters

Radio Propagation Calculator is a lightweight Windows application designed to help you calculate the transmission path between an RF transmitter and a receiver.

General presentation and usability


This makes the utility useful for various free-space and space-wave-related applications such as those encountered in VHF, UHF, and microwave communications, as well as satellite-based communications.
In short, Radio Propagation Calculator (or RFProp) is a utility for calculating the signal characteristics of radio propagation paths.
Since paths are always clear when it comes to these types of scenarios, the app also includes a precise diffraction calculator that, when enabled, allows you to take into account geography-related obstructions.
It includes a series of complex algorithms for line-of-sight, through-building, and obstructed (diffracting) paths, as well as free space.

GUI rundown


The app features a slightly old-looking GUI, yet it gets the job done quite nicely. The main window of RFProp displays the scenario of a radio transmitter of a receiver, as one might expect.
It can also display the scenario if the receiver and transmitter are separated by distance, as well as various obstructions (hills, mountains, etc.).
In short, the GUI is designed to allow you to conveniently navigate around various parameters when experimenting with a wide array of options. Once all the data is entered in its specific location, the app will display the results in the lower part of the main window.
It's worth noting that a series of detailed results are offered in a separate text window. To access this text window go to File -> Text Window.

Conclusion


Even though Radio Propagation Calculator is not useful in terms of general usage (meaning not many users will be particularly interested in it), it does its job valiantly.
It lightweight, easy to use, and the results are quite accurate. It provides you with a simple way of both calculating and visualizing the transmission path between an RF transmitter and a receiver.
