Its strange that I don't recall seeing that Cebik article before, I'm pretty sure I read them all at one point or another...


I was never fond of the 5/8 over 1/4 or 1/2 collinear idea.  I think part of it was I was worried about how the extra 1/8 wavelength of out of phase currents would mess with the collinear effect...


There is also an optimal length for said collinear sections to be apart, and in most cases, the 1/2 over 1/2 wavelength or 1/2 over 1/4 wavelength setups are naturally very close to said optimal distance between current nodes to begin with. Putting a 5/8 wavelength section on top instead would necessarily push said points even further apart countering any said benefit some people have set in their minds that they would get from using a 5/8 wavelength section, or so I think...


But then I have my own thoughts on what vertical is better for what, and with who I am responding to, I would just be preaching to the choir I think...
