Drone Range Calculator

Estimate max radio/video range using the Friis line-of-sight formula

Transmitter output power in milliwatts
Antenna gain in dBi (2-5 typical)
Receiver sensitivity (negative dBm)
e.g., 2400 (2.4GHz), 5800 (5.8GHz)

Estimated Range (Line-of-Sight):

Enter values and click 'Calculate'.

Note: This is ideal line-of-sight range. Real-world range is reduced by obstacles, interference, and multipath. Always fly within VLOS.
