Note To The Open Field Site Characterization

Abstract

Aktract-This paper presents results of the characterization of five different, qualified Open Area Test Sites (OATS). These sites were evaluated using the site attenuation procedure from MP-4 [l] and a large EUT. Significant deviations in the emissions levels from the EUT were observed. These were found to correlate with the deviation in the height of the receive antenna in the site attenuation procedure relative to the theoretical height. It is recommended that the deviation of the receiver antenna elevation be calculated during site attenuation measurements. . This parameter may be used to quantify the anomalies of the OATS, give an objective measure of site to site repeatability and validate the volumetric site attenuation process.
