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
