Greetings Ed!   
      
    LF>>> A director leads an orchestra when playing music. Radials are those   
    LF>>> "elements" that are excited when radiating RF. The only thing   
    LF>>> confusing about this are the molecs who're heating up those radials   
    LF>>> because of their activity.   
      
    HG>> The exited elements are named radiators or driven elements.   
      
    RW>> Yes, in a yagi or dipole.   
      
    HG>> The reflector(s) and director(s) are parasitic elements.   
      
    RW>> No, they're mirrors and orchestra leaders. I think of your   
    RW>> version of reflectors as RF image deflectors and your directors   
    RW>> as RF guidence elements. Especially in a yagi antenna. Not so   
    RW>> much as in a LPDA, as only some of the elements are excited,   
    RW>> while those which are not in use for a radiated RF signal at a   
    RW>> frequency in the design limitations of the particular antenna   
    RW>> are not.   
      
    EV> Howdy! Roy, Lisa and Holger,   
      
    EV> On page 609 of my copy of the A.R.R.L. The Radio Amateurs Handbook,   
    EV> 1976 version.   
      
    EV> Under the Topic "DIRECTIVE ARRAYS WITH PARASITIC ELEMENTS"   
    EV> Sub-Topic "Parasitic Excitation"   
    EV> In the Second Paragraph it has the words "parasitic", "director" and   
    EV> "reflector".   
      
    EV> Did the A.R.R.L delete that info from the 1977 'Handbook' You have?   
    EV> I Think Not!   
      
   But, the subject of 'Directive Arrays with Parasitic Elements' is all   
   about Antennas and the author assumed that everybody who reads it knows   
   the nomenclature. Had a person with no antenna knowledge at all, they   
   could just as easily have been misled by the use of those words.   
      
    EV> 73, or is that suppose to be Ten Roger Good Four Buddy?   
      
   30-12 GB or if you're more advanced, then it is 60-24 MGB...   
      
      
       Have a day!
