This equation calculates power density at a specified distance using power to the antenna and antenna gain.
Used to calculate power density at a specified distance using EIRP.
Calculate antenna numeric gain from dBi or numeric.
Calculate EIRP or ERP from field strength.
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)
Used to calculate a value when the limit changes with the logarithm of the frequency.
Calculates antenna gain from field strength, power to antenna, and distance.
