Quality control of antenna calibration and site-attenuation data from open area test sites

The use of swept-frequency methods coupled with some computation and graphics display capability, plus an understanding of the behavior of anomalies during data processing, is shown to provide an effective way to detect erroneous or suspicious data from antenna calibrations using the standard-site three-antenna method specified in ANSI Standard 63.4 (American National Standards Institute). How data from antenna and site calibration can be used to cross-check their own accuracy is demonstrated. With appropriate software, the evaluation can be done on site, immediately after the data have been taken. The same tools can be applied to evaluate the validity of site-attenuation data
