gain is specified in dBiL, you must subtract 2.15 dB to obtain its gain in dBd units. For circularly polarized
antennas, you should use the maximum linear gain in any orientation. If this is unknown, it can be
calculated using the antenna’s circular gain and axial ratio. If the axial ratio is unknown, the maximum gain
can be approximated by subtracting 3 dB from the circular gain if the beam width in both the horizontal and
vertical directions are equal.
