Feature List

Terrain-aware coverage

Signal heat maps combine free-space loss with knife-edge diffraction over Mapbox elevation — shadows and valleys behave like the real world, not a flat circle.

Link & path analysis

Per-link terrain profiles with Fresnel zones 1 & 2, 60% clearance, earth-curvature correction, and a full link budget (FSPL, gain, cable loss, margins).

Per-node antennas

Height, gain, 3 dB beamwidth, heading and front-to-back ratio — each node configured independently, with pattern presets.

Works on your phone

A mobile-first map with tabs, on-map quick controls, long-press node menus, address search, and a distance measuring tool.

Bring your own elevation

Mapbox Terrain-RGB, USGS 3DEP, OpenTopography, Open-Elevation and OpenTopoData — pick the source that fits your region and accuracy needs.

Save & share

KML import/export, PDF reports, and optional cloud sync of sessions and settings across devices.
