You can get an absolute calibration by the reciprocity
method, using two identical antennas. An extension of
this technique is the 3 antenna method which gets rid
of the assumption that the antennas are identical, by
doing 3 pairs of measurements.
In the reciprocity method, you transmit on one short
vertical and receive on the other. The gains can
then be determined by the usual path loss equation.
