This has all been very fun to read, lively strand to say the least!


But I am curious about one thing, Donald; How does this Vector design defy vertically-stacked collinear gain theory? In this "non-apparent collinear" the alleged current maximas aren't spaced the 1/2 wavelength apart needed for 2dBd?

The graph shows maybe .5dBd for 1/4 wave spacing of 2 full 1/2 wave dipoles, but the lower one of these two in your Dominator & the Vector design is only HALF of a 1/2 wave dipole.

At what distance were these tests performed?
