 2. Test Procedure
Equation from page 18 of OET Bulletin 65, Edition 97-01




      Where:
             S = power density
             P = power input to the antenna
             G = numeric gain of the antenna in the direction of interest relative to an isotropic radiator
             R = distance to the centre of radiation of the antenna
