Calculators

Power Density (Antenna)

This equation calculates power density at a specified distance using power to the antenna and antenna gain.




Power Density (EIRP)

Used to calculate power density at a specified distance using EIRP.




Antenna Gain Conversions

Calculate antenna numeric gain from dBi or numeric.



Radiated Field Conversion





EIRP and ERP from dBuV/m and distance

Calculate EIRP or ERP from field strength.








Unit Conversion dBm/mW



Unit Conversion dBuV/uV



Distance Corrections in dB

Used to calculate factor for adjusting limits or field strengths for frequencies below 30 MHz (40 dB/decade)




Used to calculate factor for adjusting limits or field strengths for frequencies above 30 MHz (20 dB/decade)




Linear Interpolation with Log of Frequency

Used to calculate a value when the limit changes with the logarithm of the frequency.




Antenna Gain Calculator

Calculates antenna gain from field strength, power to antenna, and distance.
