What is EIRP formula?

EIRP = P_Tx - L_Tx + G_Tx For example, a transmitting station has 1000 W (or 30 dBW) as its transmitter output and uses an antenna with a gain of 10 dBi. The cable to the antenna introduces a 3 dB loss to the signal. The station EIRP would be: 30 dBW - 3 + 10 = 37 dBW (5011 W).

How is EIRP wireless calculated?

Now looking at the formula with a the additional information factored in you would see the following: EIRP = transmit strength (dBm) + antenna gain (dBi) – cable loss (dB) Now you can check out the last post and put the pieces together.

How do you calculate ERP power?

To calculate ERP, Take the transmitter power output, subtract the losses from the duplexers, subtract any measurable feedline loss and add the antenna gain. Example: (2 dBd combined duplexer and feedline loss) + (5 dBd antenna gain)= 3 dBd gain.

What is EIRP measured in?

radio communication transmissions

remote receiving antenna is the effective isotropic radiated power (EIRP), measured in watts per metre squared. To achieve high EIRP the antenna dimensions should be several times larger than the largest transmitted wavelength.
