This calculator shows the theoretical attenuation with no terrain considerations. Again, you can enter a value for Distance and see the Attenuation, or alternatively enter a value for Attenuation, to see the maximum Distance.

Attenuation = 36.6 + 20 x log(D) + 20 x log(F)


F - Frequency



D - Transmission distance

A - Attenuation (dB)
