TerrainLine of sightFresnelReport
Planning estimate: terrain and Fresnel effects make this considerably more realistic than circular range rings, but results still require field verification. Building data, exact antenna patterns, polarization mismatch, local RF noise, and foliage moisture are not fully modeled.
Elevation and current weather context are retrieved through Open-Meteo. The propagation calculation is performed locally in the browser. This implementation uses terrain profile obstruction and diffraction approximations; it is inspired by engineering propagation principles but is not a certified Longley–Rice/ITM implementation.
