This is the 4NEC2 antenna bend model for: Dipole Slope
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 the Length (L=) of the dipole
wire at the Slope Angle (ang) of interest.
4NEC2 is an NEC2, NEC4, Windows based antenna modeler and optimizer by
Arie Voors.
