Greetings TOM!   
      
      
    RW> TW>> All antannas are built form some Schematic or theory Drawing   
    RW> TW>> aren't they?   
      
    RW>> Not always...I have the makings of a LPDA in my shop, that will   
    RW>> require me to cut the elements as I assemble them to the booms. The   
    RW>> only drawing is one that I used to help me see it in my mind. No   
    RW>> theory, just lengths and spacing dimensions from an experimental   
    RW>> antenna built years ago.   
      
    TW> IF you used "Cut and try" to determione the length that is how you   
    TW> Developed the "Theory" of your antenna.   
      
   I could just as easily figured what they should be from a formula, such   
   can be found on that page where you're getting your 'schematic' idea of   
   the antenna.   
      
    TW> And you built another one form that "Theory".   
      
   Whatever.   
      
    RW>> models is called - KLM-27el-UHF-BandPass-Antenna, Model   
    RW>> KLM-420-470-27.   
      
    RW>> The model number speaks for the antenna;   
      
    RW>> Manf - KLM * Band - 420-470MHz * Elements - 27 * Length 120" aka 10   
    RW>> Feet.   
      
    RW>> It has 4 elements that are considered to be LPDA, while it has 23   
    RW>> parasitic elements that are called directors with one reflector.   
      
    TW> the one I am talking about has NO directors or Reflectors as in a   
    TW> Standard YAGI   
      
   Link!   
      
    RW>> The 4 element 'dipole array', are seperated and fed with the cross   
    RW>> links as you describe, but the factory labels them as 'phasing   
    RW>> straps'...   
      
    TW> ALL elements, 7, on my antenna are seperated and fed with the cross   
    TW> links, phasing straps, or whatever you want ot cal them.   
      
    TW> It is not a YAGI   
      
   It is not a LPDA...   
      
       Have a day!
