Abstract :
Normalized site attenuation, or NSA, when it is observed in free space is a function of the characteristic impedance of free space, the characteristic impedance of the measuring system, the radiation wavelength, and the distance from the source of radiation to the observation point. NSA can be similarly characterized on the ideal open-field test site by defining the effective distance from the source to the observation point. For horizontal polarization, numerical results obtained here agree with those of the American National Standards Institute (ANSI); however, the results do not agree for vertical polarization
