Parabolic antenna gain
To use the calculator you need to enter any three of four values and the calculator will compute the fourth one (if it is mathematically possible). Remember to select proper units and click the [Compute] button which is connected to field you want to evaluate.
- A/d - size of antenna aperture (as an area or as an diameter)
- λ/f - wavelength or frequency
- e - aperture efficiency (as a value [0..1] or percent)
- G - antenna gain (as a dimensionless quantity or as dBi value)
