I don't think i missed something Eddie, i posted the link for anybody interested in what it says,
The part about nec 2 & 4 is just something i noted that could be causing you some issues with agt,
you had a long dogbone that does not work in practice with the tube diameters im using,
The info about stepup ratio with different diameters & spacing told me I needed to narrow the spacing to lower the Z0 of my gamma section,
I flipped the clamp over on the dogbone which sets gamma close to parallel,
& because my 50mhz versions are using relatively fatter tubes than any 27mhz version i decided to start with the longest rod & shortest tube to reduce gamma diameter,
It worked,
If somebody converts a v4k to my dimensions,
places it 1/4wave over average ground & adjusts the gamma capacitor, they will get a low vswr & a wider vswr bandwidth like Vortex claim,
im still waiting to see the extra signal strength,
when you look at their other crazy claims & what happens with widebanded j-poles when you extend the short leg i doubt i will see extra signal but i could be wrong, more tests needed,
its snowing im not messing with antennas.
