Abstract: This handbook is intended to provide estimates of radio wave propagation loss between transmitting and receiving antennas of various heights and transmission frequencies above the assumed smooth–earth surface calculated using the NLAMBDA computer model. For many cases involving electromagnetic compatibility analysis, the curves of predicted transmission losses in this report may be used to estimate the transmission losses of the desired and undesired signals. These estimated 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 20,000 MHz frequency range, over land or sea, at great circle earth surface distances up to 1000 kilometers. This handbook is an expanded version of the initial handbook2 and includes curves for the additional frequencies of 500 MHz, 2000 MHz, 5000 MHz, 7000 MHz, and 20,000 MHz.
Keywords: electromagnetic compatibility (EMC); basic median transmission loss; radio wave propagation; transmission loss
