Abstract

Narrow- and broadband measurement systems have been calibrated and used to characterize the electric field strength in regions close to 69 telecommunication antennas emitting a total power of nearly 190 kW. The differences in decibels between narrow and broadband outdoor measurement results are always within 0.71 dB, giving a mean value of 0.08 dB. An error analysis referring to the use of both measurement systems has been done. From a statistical analysis of the obtained results, the assigned total systematic error of the isotropic electric field measurements in the frequency domain is 1.82 dB for both systems. The inherent systematic error in the measurement procedure is about 1.57 dB
