What it calculates
The “Drone link range” calculator computes Link range (theoretical) in km from 5 parameters: frequency (MHz), transmitter power (dBm), antenna gain (total) (dBi), receiver sensitivity (dBm), fade margin (dB).
A handy everyday calculator for daily tasks.
Example calculation
With parameters Frequency = 2,400 MHz, Transmitter power = 20 dBm, Antenna gain (total) = 4 dBi, Receiver sensitivity = -90 dBm, Fade margin = 10 dB the result is 1.58 km (Clear line of sight, no obstacles (Friis formula)).
