The Effective Isotropic Radiated Power formula calculator is an online conversion tool for calculating the Effective Isotropic Radiated Power of an antenna.
EIRP Formula Equation
EIRP = PT – LC + GTX
Where in the above equation:
- EIRP = Effective Isotropic Radiated Power (expressed in dB)
- PT = Radiated power of the antenna in (expressed in dbW)
- LC = Signal loss caused by the cable from the transmitter circuit to the antenna (expressed in dB)
- GTX = Gain of the transmitting antenna in (expressed in dB)
What is EIRP
EIRP is the abbreviation for Effective Isotropic Radiated Power. The term is very often used in the field of Electrical, Electronics, and especially telecommunications engineering to describe the amount of power that a radio transmitter radiates in one specific direction. The EIRP considers the transmitter power, antenna gain, and efficiency of the antenna.
EIRP calculator by Electrical Calculators org lets you calculate the value of EIRP in dB from the know values of the transmitter’s radiated power, the losses resulting from the cable from the transmitter to the antenna, and the antenna’s gain.
