I don't like the 5/8wave & its 1/8wave out of phase radiation cancelling some of the benefit it has in raising the upper 1/2wave higher above ground,
There is a better way,

as you say when its the upper part of a collinear that unwanted 1/8wave is also moving the current maxima further apart, I thought that would be a bonus,

ad the fact that the G-MAX lower radiator is about 147" & not 1/4wave
the currents are even further apart,

I was under the impression that optimum spacing for 2 end to end elements is close to .9 wavelength,
The G-MAX seems to be in the ballpark for spacing of current maxima on the two radiators, Less than .5db down from optimum spacing,

am I missing something ?

If I remember correctly Henry's Highlander had about 1/2wave upper radiator with a longer/taller phasing coil & also had a longer than 1/4wave lower radiator.

Thanks
