This has kind of bothered me for a while, ie drawing out the measurements for use by anyone. There are so so many models ! It seems like the simplest solution may be is to go right to the source. I dont really think its that hard. (at least in Windows XP, Im having my son work on the Linux solution, heh)
By using this method, the models on this forum can be shown in a whole new light for typical users.
- Download and install the excellent free forever 4nec2 program from Arie Voors site at http://home.ict.nl/~arivoors/
- also download and install the 4nec2 3d extension if you have any kind of recent video card at all, which Im sure you must, heh
- In the Main Tab, click Settings option, make these adjustments:
- set Char-Impedance to 300 (actually this is optional)
- set Length unit to feet, inches or meters, what ever you prefer to use.
- set Radius unit to inches/AWG or Millimeters, what ever you prefer to use.
- set to Geometry edit
- Copy and paste the NEC code data that is posted to a .txt file.
- Rename the .txt file to a .nec file (ignore the warning, heh)
- In the Main Tab, File > Open 4nec2 in-/output-file (name of the renamed .txt to .nec file)
- In the Main Tab, click Edit > Input(.nec) file. (that .nec file)
- In the Geometry Edit screen, choose either 3D, XZ,YZ, or XY button depending on the view of the antenna you want.
- Note: in the 3D view you can twirl the antenna around holding the left mouse button down and moving it.
- Click on the antenna element in question. To the right will be shown the Length and Wire Gauge or radius of the element.
- You can also quickly deduce the spacings.
