Greetings Holger!   
      
    HG>> This antenna has been fully described in the Ham Radio magazine with   
    HG>> element lenghts for various bands of frequencies.   
      
    RW>> Perhaps, but who reads magazines these days? Formulas for finding   
    RW>> the lengths of elements and booms are available on the internet and   
    RW>> readily used to design any LPDA for whatever use you have in mind.   
      
    HG> Well, magazines have a longer shelf life than any electronic media I   
    HG> know of.   
      
   With the advent of a means to safely store everything that you could want   
   to save from a magazine or an internet site, you have the ability to   
   access that same info and illustrations at a moments notice, rather than   
   poke around a pile of old paper that has deteriorated beyond heavy use.   
      
   I have old Dectective magazines that are too fragile to even thumb   
   through.   
      
   Meanwhile, the shelf life of modern media these days is beyond anything   
   that you can have in a magazine. i.e. a CD recorded in the very early days   
   of digital media is still as vibrant as it was back then.   
      
   The pages of my 1977 Antenna Handbook are stiff and easily torn. I expect   
   it to turn to dust before I'm not around to use it. Not to mention the   
   bookworms.   
      
   I also have my 1st ever Amateur Radio Handbook from 1964, but it is too   
   fragile to handle these days without damaging the so often referred to   
   antenna information pages I used back then.   
      
   Last but certainly not least is the fact that if something I had saved to   
   digital media has been lost or damaged, that info is still available on   
   the internet with a simple Google search. There I have a choice of   
   umpteen places that not only have saved it, but have update comments   
   galore...   
      
      
       Have a day!
