Greetings Holger!   
      
    RW>> Which doesn't speak to the fact that the LPYA isn't really a LP   
    RW>> antenna, but a yagi with a driven section like the LPDA and 23   
    RW>> parasitic elements like a yagi. A true LPDA would have 27 active   
    RW>> elements with no parsitic elements.   
      
    HG> The number of parasitic or active elements are a moot point in the   
    HG> discussion!   
      
   Actually, the use of active elements is predominate in the discussion of   
   these two different antennas. One is active throughout and the other is   
   not.   
      
    HG> KLM makes log-cell fed yagis with different number of elements.   
      
   That's what I said. The rest of the elements used are parasitic and   
   nothing more. Without the log part, the yagi parasictics wouldn't have the   
   bandwidth that it does have.   
      
    HG>  Most of them do use a LP fed cell of four driven elements   
    HG> to broaden the frequency range (bandpass).   
      
   Of course.   
      
    HG> The antenna Tom has is apparently based on the same design philosophy   
    HG> but instead of parasitic elements the number of phased driven   
    HG> elements are increased.   
      
   Meanwhile, it isn't even in a class that could be called a LPDA.   
      
      
       Have a day!
