Your method is certainly one way to do it, but there are far simpler ways. The link below describes the one I think when you say "inverted L." His discussion is quite solid from an engineering point of view. http://www.eng.mu.edu/~usi/invertedl.html I agree with all of his comments re: ground system and maximizing the vertical portion. His selection of overall length to make it load well on several bands is also intersting. In essence, the overall length makes the antenna easier or more difficult to load, and the vertical section produces the most useful radiation. Also, the distribution of current on the vertical section, as well as the interaction of the vertical section with the earth around your station, are mostly what establishes the vertical pattern (that is, high/low angle). What I think you are doing by varying the length of those horizontal sections near the ground is putting the current maximum on the vertical section so that it produces the nicest low angle pattern. 73, Jim Brown K9YC _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
