   Hi Roy,   
      
    HG> Behind the stack of driven elements there usually is a reflector and   
    HG> in front of the driven elements directors.   
      
   RW>That's the theory, anyway. And the one that Tom is advocating. IMO,   
   RW>it is not a true LPA.   
      
   HG>That's not theory only, it is a working concept proven over the years   
      
    HG> This antenna is often called a KLM-yagi because the KLM company was   
    HG> the first to manufacture antennas of thes kind originally presented   
    HG> in an article in QST.   
      
   The antenna Tom is describing was originally described as 'The Swan   
   Multidrive 2-Meter Antenna' in QST October 1969. Because of previously   
   told reasons it's now called a KLM-yagi.   
      
   As presented in that QST it was fed with an open 1/2 wl line with a   
   sliding short and coax with a balun tapped at a point of the open line.   
      
   That was also the way I built my first version. Later versions were fed   
   with coax through a bazooka as a more rugged solution.   
      
    HG> The other kind of LPA is one built on two booms insulated from each   
    HG> other and fed from (often) the front end.   
      
   RW>Correct and this is the subject of this LPA discussion.   
      
   HG>The discussion seems to have gone astray somewhere.   
      
      
   CU AGN,
