If I remember my traveling wave antenna theory, he wouldn't necessarily be

radiates before it gets to the loads, does it not?

Hi Jim,

You are right (losing - unless it has diarrhea). What is described is
a vertical, half Rhombic, a Military application for many years. This
report appears to be about a design from yet another "inventor" who
has "discovered" something that confounds the experts.

The original poster asked for comments, especially about the resistor
(the difference between shorting it and loading it) however, nothing
is said about ground. Both of the resistors will require radials,
however, there seem to be more specifics missing than that.

In other words, what is the leg angle subtended at the fed point? Why
not simply feed one end and terminate the other? Seems like a pain to
elevate the feed point without some analysis showing why - but then it
appears the column was painfully shy of anything technical beyond
carpenter scaling.
