This is the 4NEC2 antenna bend model for: Standard Horizontal V-Dipoles
To use this model:
Below. Highlight and copy (Ctrl C) the program control codes (CM,
CE, SY,etc).
Open Windows Wordpad and copy (Ctrl V) the control codes into Wordpad.
Go to "File, Save as..." and name your new antenna model.
In Windows Explorer, right-click on your new model and "Rename" the file to end as ".nec".
Open your new model to optimize Length (L) for various angles of
bend (Symbols, "Ang=").
4NEC2 is an NEC2, NEC4, Windows based antenna modeler and optimizer by
Arie Voors.

CM Standardized V-Dipole, 1-feed
model for comparison studies.
CM #14 AWG. Feed point at 1/2 wavelength over ground at 28.4 mc.
CM Fixed ratio creates only 1 segment in center at feed point.
CM For V-dipole analysis at any angle, arms up-or-down
