Calculate the wave length of the waves produces by the antenna. For an average 8 foot antenna mounted on an average vehicle, and using an estimated ground losses, the efficiency ranges between.2% on 80 meters to maybe 80% on 10 meters. These figures are based on data taken from Chapter 16 of the ARRLAntenna handbook. Antenna gathers the energy of an incident electromagnetic field. A — collecting area, Ae — effective aperture, E — electric field, H — magnetic field This calculator determines the effective aperture Ae for a given frequency f or wavelength, λ and antenna gain G. Antenna efficiency is also frequently quoted in decibels (dB) ; an efficiency of 0.1 is 10% or (-10 dB), and an efficiency of 0.5 or 50% is -3 dB.

4. A transmitting antenna with a gain of 3 dB means that the power received far from the antenna will be 3 dB higher (twice as much) than what would be received from a lossless isotropic antenna with the same input power. Note that a lossless antenna would be an antenna with an antenna efficiency of 0 dB (or 100%). Online Antenna Arrays Calculator to calculate antenna array factor,The calculator will calculate the Antenna Gain for given values of efficiency, wave length, physical aperture area.
