Path testing for microwave-radio routes

IN PLANNING the construction of a microwave-radio relay system, it is of utmost importance that the sites for the terminal and intermediate stations be so selected that undesirable radio-propagation conditions are avoided. At the same time it is desirable, for reasons of economy to minimize the number of intermediate stations required, and to utilize the smallest towers which will give satisfactory radio transmission. In order to achieve these objectives great care must be exercised in the selection of the station sites.
