Calculate Peak Gain

This tool calculates peak gain based on the following parameters:

• $f=$ frequency and frequency units

• $D=$ dish size $(\mathrm{m})$

• $\eta =$ efficiency

• ${\mathrm{G}}_{\max }=$ peak gain $(\mathrm{dBi})$

These parameters are related using the following equation:

$$G_{\max }=\eta {\left(\frac{\pi Df}{c}\right)}^2$$
