I was particularly impressed by the consistency of the vertical with one counterpoise. Looking a the lengths of the radiator and the counterpoise is this simply a random length wire mounted vertically?

I guess one could look at it that way… The performance of this arrangement has impressed me as well, especially since the radial was lying in the grass and not elevated. What wasn’t mentioned in the PDF is that the KX3 was placed right at the base of the pole, so the radiator wire coming down from the mast could be connected directly, without any balun or coax whatsoever. This may not always be convenient.
