I put 27.205 mhz into the calculator and the result for the phasing stub shows about 103" inches. Do you think that means to double it over?


A J-Pole has a 1/4 wave tuneing setup at the bottom like the Vector, why would it be different if made collinear. Since it showed the stub was only 103" I figured the thing was a 1/4 wave like you were claiming for the S4. Did I read it wrong?


Maybe I did read it wrong, the picture indicates a 1/2 wave phasing setup.
