   Hi Roy,   
      
    TW>> but about Balun Matching or 1/2 wavelength Coax matching a dipole   
      
    RW> Baluns are used to tune the antenna to 50ohms. A 1/2 wavelength of   
    RW> coax isn't matching the antenna to anything.   
      
   No, because a 1/2 w/l (incl. velocity factor) of coax just repeats the   
   same impedance at the other end.   
      
   RW>I've experimented with the idea that any length of coax in 1/4 wave   
   RW>increments can be used to match a load, but that isn't true.   
      
   You can transform impedance with a 1/4 w/l of coax of another impedance   
   to an impedance that may be more useful.   
      
   But you can never TUNE an antenna with any sort of feedline.
