Book Description
In this report, descriptive and statistical analyses of radio propagation data over irregular terrain in approximately the 100- to 10,000 -MHz frequency range are presented, with special emphasis on communications between low antennas in the 225- to 400- MHz band. Data are evaluated in terms of medians and ranges of basic transmission loss, height gain, frequency dependence and effects of vegetation. Graphs provide first estimates of these parameters for specific applications in many terrain types. The results also provide information for verification and improvement of previously developed more general propagation model.

Book Description
This is the fourth part of a four-part report containing tabulations and graphs of transmission loss data resulting from propagation experiments in the 230- to 9200- MHz frequency range conducted over irregular terrain in Colorado. This part presents data obtained at a common receiver site, located in a small grove of cottonwood (Populus deltoides) trees, over propagation paths varying in length from 0.5 to 50 km.
