This annexure relates to regulation 6(2) of these Schedule D Regulations. The intention of the information provided in this annexure is to assist persons involved in the determination of the propagation path loss required to determine the separation distance. The information is not meant to be prescriptive or limiting of the standards and techniques that may be used and that may provide results with a higher level of accuracy. The options stated may be considered as the minimum standards to be applied to calculate the propagation path loss.
