This is the 4NEC2 antenna bend model for: Standard Lateral 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=) \("Ang=").
4NEC2 is an NEC2, NEC4, Windows based antenna modeler and optimizer by

CM Standardized Lateral V-Bend
model for comparison studies
CM #14 AWG. Feed point at 1/2 wave over ground at 28.4 mc.
CM Fixed geometry so only 1 segment in middle as feed point - do not
change!
CM For V-dipole study at any angle Side-to-Side (LATERAL)
