   Greetings TOM!   
      
    RW> TW>> What i am desctibing is build directly using the LPDA antenna   
    RW> TW>> Theory Drawing on hte Internet.   
      
    RW>> Link?   
      
    TW> I sent a Liknk before and you apparently Ignored it.   
      
   I don't remember link from link...   
      
    RW> TW>> And is an Absolute copy Theory Wise as what you are talking   
    RW> TW>> about except for the using of a single boom with all the   
    RW> TW>> elements insulated from the boom and uses wiring in place of the   
    RW> TW>> Two Booms which perfom the same purpose as the wireing in the   
    RW> TW>> antenna I am talking about   
      
    RW>> That isn't LPDA theory...LPD antennas include the boom as an active   
    RW>> part of the antenna. What you've done is isolate the boom(s) from   
    RW>> being an active part of the antenna and only using the dipoles. I   
    RW>> really can't see building such a monster, when it is so much easier   
    RW>> to build a LPDA...   
      
    TW> Only the one you are talking about has two booms with the Boons being   
    TW> a part of the feel line to the elements.   
      
    TW> I have one of the antennas I am talking about on my roof constructed   
    TW> from the Pure Origional LDPA theory drawing,   
      
   You mean the schematic of such an antenna. Pure LPDA is built with two   
   booms and follows a formula, which is where the LP comes from.   
      
    TW>  Which I perviously linked,   
      
   Link?   
      
    TW> where all the elements are insulated from the support boom   
    TW> and are connected by a crossover wiring system, as in the theory   
    TW> drawing, so All elements are connected to the coax. Half to the   
    TW> center conductor and half to the Shield.   
      
   With each element isolated from the others as the schematic shows?   
      
   I don't think so.   
      
       Have a day!
