Wbando vs Terrain Elevation Profile

Every failsafe has a reason. Wbando is tactical flight intelligence for FPV pilots. Before you arm, it maps the invisible forces that cause failsafes — terrain shadows, tree-canopy attenuation, RF interference, and Fresnel-zone clearance — so you know where your link will hold and where it won't. IT STARTS WITH LINE OF SIGHT Your radio signal travels in a straight line — that's where the marketed range numbers come from. Clear line of sight means full control. But the world isn't flat. THEN THE TERRAIN GETS IN THE WAY Terrain casts a radio shadow — and what you can't see on a flat map can kill your link. Wbando scans global elevation data (30 m resolution, 195+ countries) to predict exactly where those shadows fall. EVEN TREES FIGHT AGAINST YOU Vegetation absorbs and scatters your signal with every meter of foliage. Wbando factors satellite-derived canopy height (10 m resolution) into every line-of-sight prediction — critical for flights over forested mountains. COMPETE WITH THE NOISE FLOOR The radio spectrum is crowded with emitters you can't see. Wbando maps thousands of cell towers, FM/AM and TV broadcast stations around your flight zone so you can plan around interference hotspots. VISUAL LINE OF SIGHT IS A LIE Radio waves travel in a thick elliptical volume — the Fresnel zone. If terrain clips it, your signal drops even when you can still see your drone. Wbando flags marginal zones before you find out mid-flight. WHAT YOU GET • Radial Scan — line-of-sight coverage around your take-off point, with elevation profiles showing exactly where terrain blocks your signal • TOFF — draw your flight trajectory and see what percentage of the path stays in coverage • RF emitter map — thousands of towers and broadcast stations around your spot • Saved spots — build a library of proven launch points • Works worldwide — 195+ countries, no local setup WHAT PILOTS SAY "Sometimes I want to fly behind a mountain, but it's hard to say how low I can go to not lose signal." — long-range pilot "It's a major task planning flights in the Swiss mountains. Often it's more of a feel than knowing how far I can push." — mountain cinematographer "It could actually prove invaluable to someone who's doing complex orchestrated flights." — drone connoisseur No account required — jump straight in as a guest and run your first scan in under a minute. Built for cinematic and long-range pilots who've already tasted a failsafe and never want another.
