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,
Go to 4NEC2. Open "Notepad Edit" (Ctrl F1) and Delete the
Paste (Ctrl V) the new control codes to replace the old codes.
(Do not "Save" this or you will lose your old model)
Go to: "File, Save As..." and create new name for your Dipole
Open your new model to optimize the Length (L=) of the dipole
wire at the Slope Angle (ang) of interest.
