In this paper, a numerical model for site attenuation is described. Both horizontal and vertical polarization are presented. Ideal site attenuation values are compared with three-dimensional (3-D) finite-element results in the frequency range required by the standards. The results show significant errors in computing 3-meter (m) site attenuation in the 30-300 MHz frequency range. New values for the normalized site attenuation are then given for 3-m measurements. Such a numerical tool can be used to optimize the performances of indoor test site such as semi-anechoic chamber.
