Abstract

As a study on electromagnetic radiation emission from the neon signs, this paper has investigated the characteristics of frequency bands and spectra intensities under the operations of the sign's OFF, ON/OFF and continuous ON states. Also we have studied the above characteristics when a distance between the sign and the antenna is varied. All data were obtained in the range of 0.1∼1,000[MHz] by using spectrum analyzer along with the loop, biconical and log periodic antenna. As the result, we found that the radiated electromagnetic waves of the sign at continuous ON states were measured only in the range of 30∼400[MHz] but those of the sign at ON/OFF states were appeared widely in the range of 2∼1,000[MHz].
