RF Free Space Path Loss

RF Free Space Path Loss Calculator

Calculate the free space path loss for radio frequency transmissions based on distance, frequency, and antenna gains.

Distance (km):

Frequency (MHz):

Transmitting Antenna Gain (dBi):

Receiving Antenna Gain (dBi):

Note: Free space path loss represents the signal attenuation between transmitter and receiver in an ideal environment without obstacles. Antenna gains are added to compensate for path loss.
