As the broadband antennas for EMI measurements, biconical antenna and LPDA (Log-Periodic Dipole Antenna) are used. In the measurement of site attenuation, the tuned dipole antenna is used for a standard antenna for both transmitting and receiving. In the case of biconical antenna or LPDA used for the measurements of site attenuation, it is necessary that the correlation between these broad band antennas, biconical antenna or LPDA, and the standard antenna, tuned dipole antenna, is well known. Then the value of site attenuation in the case of the broadband antenna is revised by the antenna facter which remove the deviation caused by the characteristics of each antenna. In this paper we discribe the analyzing method of the site attenuation in the case of LPDA used for receiving, present the calculated results by the method and compare them with the values in the case of tuned dipole antenna used.
