At higher frequencies more of the power radiates before it gets to the loads, does it not? Jim N8EE 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. 73's Richard Clark, KB7QHC |
