IF no one minds I'll inject this...

  • if a 50 ohm load shows low SWR on a meter - I hope we're not considering the Dummy load as Self-resonate.



Bless you...


Because of this - many consider the viewpoint of 1/4 LENGTH as being resonate - even though there's 75% of the other stuff is still missing...


So yes, along comes the coax and the counterpoise to the rescue ...

What I find interesting; as this evolves, as we "build this antenna" the SWR then tends to be a correlation to the Feed point impedance - as you adjust the opposing elements' ANGLE the shield is connected to - you can obtain the "low SWR" oriented like I had shown earlier - apply the notion that both elements are 1/4 wave in LENGTH.  You and your antenna, in free air, you can acheive LOW SWR not by changing length - but by changing ASPECT (orientation) of the elements to each other.


Oops, better add this...


Center-Fed - of course...
