   In a message dated 05-19-14, Tom Walker said to Holger Granholm:   
      
   Good morning Tom,   
      
   TW>I cannot come up with any pictures on the interent of a Yagi that loks   
   TW>like my Picture ! in my previous posts.   
      
   The Swan Yagi for 2-meters was presented in the 1969 Oct. issue of QST.   
      
   TW>YES a multipuls band Yagi will have different director lengths but they   
   TW>are the same length for each band and do not follow the full tapering   
   TW>lengths of the LPDA   
      
   The Swan (KLM) Yagi is not a multiple band yagi but a yagi with a wider   
   bandwidth (and slightly more gain) than a standard yagi with the same   
   boomlength.   
      
   The REAL LPDA can for example cover a band of frequencies from 140 to   
   450 MHz.   
      
   CU AGN,
