   Hi Tom,   
      
   HG>TW>The Create CLP-5130-1N LPDA antenna has Transmit capabilities for 50 to   
   HG>TW>1300 Mhz with a SWR of 2:1 or less   
      
   HG>Yes, a real LPDA can be made to cover almost any frequency span.   
      
   TW>And no matter the implimentation, Double boom or Single boom with   
   TW>insulated elements and crosssover wiring it is Still a Real LPDA   
      
   Nope, a real LPDA always has two booms and the feed is connected to the   
   front of the antenna with the braid to one boom and the inner conductor   
   to the other boom.   
      
   The front of the antenna is of course the end of the antenna with the   
   shortest elements.   
      
   The Swan (KLM) antenna presented in QST was called "a multidrive yagi"   
   antenna. No mention of log periodic was mentioned. The driven elements   
   are insulated from the boom because of the crossfeeding but the other   
   parasitic (reflector and directors) elements are mounted directly on the   
   boom.   
      
   If you are a collector of magazines you may have the QST Oct. 1969 issue   
   where the original presentation was made.
