Unusual Propagation Factors in Point-To-Point Microwave System Performance

Practical problems in the microwave propagation field, which are considered extraordinary and are largely related to ground reflection phenomena are explored. The effects of these problems in terms of noise, discontinuities, and delay distortion, with the attendant unsatisfactory transmission of telephone message, data, and television signals, were the motivation for the studies described, The solutions in terms of extra structures and, in one case, space diversity, are not considered general solutions, but rather, those arrived at and proven successful in the cases covered by the study. Considerations of structure dimensions and limitations are discussed. In the space diversity case described, a method of determining antenua spacing intervals is given, and the results reported.
