Free-Space Path Loss Calculator
This calculator is used to predict the theoretical attenuation between two antennas in free space by entering the distance, frequency, and antenna gains.
Calculations:
| Distance: | |
| Frequency: | |
| Transmit Antenna Gain: | |
| Receive Antenna Gain: | |
Formula:
d = Distance between the antennas.
F = Frequency
G (Tx) = The Gain(dBi) of the Transmitting Antenna.
G (Rx) = The Gain(dBi) of the Receiving Antenna.
c = Speed of light in vacuum (Meters per Second)
* All conversions are based on free space conditions (impedance of 377 ohm)
