Plan 5.8 GHz FPV channels for up to 6 simultaneous pilots. Flags conflicts where channels are too close (<40 MHz separation causes crosstalk).
Add at least 2 pilots to see conflict analysis.
Every transmitter on the airframe generates harmonics. Check for interference with FPV video channels AND GPS/GNSS receivers. Applies to C2 links, telemetry radios, video TX, mesh radios, and any other RF source.
Friis transmission equation link budget for FPV and control link. Calculates usable range from TX power, antenna gains, frequency, and receiver sensitivity.
The first Fresnel zone must be 60% clear of obstructions for a clean RF link. Calculate maximum zone radius at any point along the path.
Calculate quarter-wave and half-wave antenna element lengths for any frequency. Account for velocity factor of coax or wire.
Find the nearest named FPV channel to any target frequency. Useful when operating on non-standard or modified bands.
Generate ready-to-paste Betaflight vtxtable CLI commands for your VTX. Select your model, copy, paste into CLI.

Real-terrain link analysis using elevation data. Drag TX/RX markers on the map. Computes path profile, Fresnel zone clearance, knife-edge diffraction, and full link budget. Uses USGS 3DEP (1m, US) with SRTM (30m, global) fallback.
Place drone nodes on the map to model MANET mesh connectivity. Computes RF propagation between every node pair, identifies weak links, single points of failure, and network partitions.
