   Greetings TOM!   
      
    HG>RW>> I used to think that way when I was an experimenting CBer c1965,   
    HG>RW>> chasing high SWR with coax lengths in intervals of 'wavelengths'   
    HG>RW>> and parts thereof.   
      
    HG>TW>> BUT it CAN be done. And while the point may be arguable I suspect   
    HG>TW>> that WHEN YOU find the Perfect length it would be less loss than   
    HG>TW>> THE BALUN   
      
    HG>> You are only fooling yourself, the SWR meter and the transmitter   
    HG>> that there is a low SWR. The fact is that the antenna is still not   
    HG>> matched to 50 ohms and you cannot tune the antenna with any sort of   
    HG>> "antenna tuner". The same bad old SWR still exists along the feeding   
    HG>> cable.   
      
    HG>> The antenna tuner is a misnomer since what it actually is is an   
    HG>> "Impedance matching network". Tuning the antenna has to be done   
    HG>> at the antenna itself.   
      
    TW> This discussion is not about "Tuners"   
      
   Actually it is. It's about matching or 'tuning' an antenna to 50 ohms. An   
   antenna tuner that Holger is talking about only fools the xmitter into   
   seeing (aka thinking) a 50 ohm load, but does nothing to correct the SWR   
   on the coax.   
      
    TW> but about Balun Matching or 1/2 wavelength Coax matching a dipole   
      
   Baluns are used to tune the antenna to 50ohms. A 1/2 wavelength of coax   
   isn't matching the antenna to anything.   
      
      
       Have a day!
