 greater were taken on Route 1 toward New Rochelle and on Route 10 toward 

 Dover.) 



various frequencies should be based upon measurements taken in the 

 suburbs. The data from the New Rochelle and Dover series have been 

 used as a basis for the points and the curve given in Figure 1. Each of 

 the circle points shows the path loss at a given frequency relative to 

 that at 150 mc for a particular location. Their spread indicates that the
