I'm duplicating a few yagi elements made from European diameter tubing.
I want to get it as close as I can but I dont want to model .
I'll compensate at the tips.
.
Question: Which will get me closest to determining the correct 'equivalent'.
Area of the cross section of the element: L X W
-or-
Volume of a cylinder: 2 pi r h + 2 pi r^2
Half-element Example
EU:
Diameter 1.18" 0.987" 0.787"
43" 51" 32"
US
Diameter 1.125" 1.00" 0.875"
36" 68" X"
Stated another way: LAWSON's Yagi Element Equivalent is closer to a surface
area approximation or a cross-sectional area approximation ?
