Counter-Drone RF Tools
Engineering calculators and reference databases for C-UAS professionals. All calculators run client-side — no data is sent to any server.
Drone Signal Database
DatabaseRF signal parameters for 27+ drone models — control frequency, video protocol, GPS bands, and recommended counter frequencies.
Jammer Effectiveness Calculator
CalculatorUnified J/S ratio and effective range analysis. Enter the scenario geometry to get both the jamming ratio at your current position and the maximum range at which jamming succeeds. Includes FHSS bandwidth penalty.
RF Detection Range Calculator
CalculatorCalculate the maximum distance at which a passive RF sensor can detect a drone's transmitter, given receiver sensitivity, antenna gain, and drone EIRP.
Free Space Path Loss Calculator
CalculatorCompute RF signal attenuation over distance in free space. Foundational for link budget analysis, jammer sizing, and RF sensor planning.
Methodology note: All RF calculations use free-space propagation models (Friis transmission equation). Real-world results vary with terrain, multipath, atmospheric conditions, and antenna polarization. Use these results as first-order estimates for planning — not as operational guarantees.
