Egli Propagation Module

The Egli module is an implementation of John Egli’s methodology published in October, 1957 in the Proceedings of the IRE. This model is derived from measured data out to a distance of approximately 50 miles and over gently rolling terrain with average hill heights of approximately 50 feet. It relies on frequency, distance and heights of transmitting and receiving antennas. It does not rely on localized path elevation data.
