Abstract
Descriptive and statistical analyses of radio propagation data over irregular terrain are presented with emphasis on communications between low antennas in VHF and UHF bands. Measured data are evaluated for medians and ranges of basic transmission loss and height gain, and results are compared with estimates from a propagation model developed by the Institute for Telecommunication Sciences. Effects of vegetation near the path terminals are demonstrated. Analysis results provide first estimates of propagation parameters in many terrain types and information regarding applicability of the propagation model.Keywords
