In this work, we discuss the accuracy of measurements for
electromagnetic. The two kinds of antenna we use are Dipole
antenna and Broadband antenna. In general, if the antenna
measurements we recorded at different frequencies do not exceed
the ideal value $pm 4$dB, we would regard this site as a
normalized site, otherwise it is not a normalized site(just a
measurement exceeds the range). Traditionally, all we use is
Dipole antenna, but due to difficulty of operation and inaccuracy
of Dipole antenna, we investigate by statistical methods if we may
use the Broadband antenna to replace the traditional Dipole
antenna to measure. First of all, we introduce the data and
procedure in the experiments, and fit a statistical regression
model to predict the measurements at different frequencies in
different test setups. Then, according to the data we collected,
use the change point models to modify the statistical models. Our
goal is to find a suitable statistical model for the
measurements. Finally, we compare the measurements of Broadband
antenna
with Dipole antenna in the other experimental conditions keep the same.
