- TX/RX height in feet (converted to meters for terrain analysis) - TX power in dBm with mW equivalent display - TX gain and RX gain (dBi) inputs - Power budget: TX power + TX gain - feed loss = EIRP - path loss + RX gain = RX power vs CW sensitivity = margin - Loss budget: FSPL + gaseous (O2+H2O) + diffraction + rain with per-km gas rate detail - GPS "Locate Me" button using browser geolocation API - Lat,lon coordinate pairs accepted as input - Weather displayed in F with C below - LiveStash preserves form inputs across page reloads - Terrain cross-section with beam line and Fresnel zone
