Common Antenna Gain Conversion Table

If you are... Calculating ERP Calculating ERP Calculating ERP Calculating ERP

And you... Start with dBi Start with dBiC Start with dBd Start with dBiL

Step 1 dBi - 2.15 dB = Y dBic - 3dB = X Keep as is dBiL - 2.15 = Y

Step 2 N/A X - 2.15 dB = Y N/A N/A

Calculating EIRP Calculating EIRP Calculating EIRP Calculating EIRP

Start with dBi Start with dBic Start with dBd Start with dBiL

Keep as is

N/A

dBic - 3dB = Y

N/A

dBd + 2.15 dB = Y

N/A

Keep as is

N/A
