* Ta = The total temperature of the antenna or array in degrees Kelvin. This includes all the side lobes, rear lobes and internal resistance of the antenna or array. A lower figure means a quieter antenna.

** G/T = Figure of merit used to determine the receive capability of the antenna or array. G/T (dB) = Ga - 10*log(Ta). The more positive figure the better. G/T is modelled in Tant.exe at 30 degrees elevation.

Other gain figures generated by NEC4 software modeling
