Being on the edge of a huge salt-water pond gives VP6DX's verticals an
advantage no "land lubber" can hope for. There's a lot of interaction
between the electromagnetic wave and the earth from a vertical antenna for
many wavelengths from the antennas. Real "earth" - dirt - is a terrible
medium. It's sort of the world's worst dielectric, even when soaking wet.
But salt water is a different story. It's a very efficient medium for the RF
to interact with.
There's a reason why so many DX-peditions like to find themselves on a small
rock in the middle of the ocean, and it isn't just for the view.
I'd bet VP6DX success is a combination of factors, salt water and
outstanding radios being two of them. That they are operating multiple
radios on the small island attests to the value of the K3. I also know
several of the ops [one has my last name :-) ] and they're all about as
good as you can get. That's another major factor. They sure are loud
here in N. Cal. VP6DI was too.
