RADIATION CHARACTERISTICS OF AN ANTENNA.

the points which have a coiniuon ratio of length of Hat-top to length 

 of total antenna. This ratio is designated by 7, where

with 



b = length of flat-top 



a = length of vertical part of antenna. 



These 7-curves all pass through the origin. 



Next as a final step the curves of Figure 14 are taken from the curves 



Figure 13. Enlarged view of some of the curves of Fiiiurc 12. 



of Figures 12 and 13 with the new set of parameters. These curves of 

 F'igure 14 are the final curws of total radiation resistance, and are in
