Abstract: This handbook is intended to assist in manual analysis techniques that must be used when an automated analysis is not possible. It provides estimates of radio wave propagation loss between transmitting and receiving antennas above the assumed smooth-earth surface that were calculated using the Integrated Propagation System (IPS) computer model. For many cases involving electromagnetic compatibility analysis, the curves of predicted transmission loss in this report may be used to estimate the transmission loss of the desired and undesired signals. These loss values are given in dB as BASIC MEDIAN TRANSMISSION LOSS for antennas with effective heights up to 5000 meters, operating in the 100 to 10,000 MHz frequency range, over land or sea, at great circle earth surface distances up to 1000 kilometers. This handbook is an initial document intended to be supplemented with additional curves that will be provided on an ongoing basis.
