A simple instruction how to create a complient FFTab from a complient antenna model file in EZNEC:

1. Create your model aligned with the x-axis of EZNECs coordinate system.

Sample antenna is a 4 x DJ9BV BVO 2-3wl understacked to 90% of DL6WU's Dopt.

2. Run a Far Field Plot (FF Plot), Plot Type = 3D with a resolution of 1 degrees:

3. Next click FF Tab to open EZNECs Far Field Table Window.
4. In the Far Field Table Window opt for Azimuth Slices and select Full Range.

5. Click the Ok button to let EZNEC create the Far Field Table.

6. Finally save the Far Field Table choosing a meaningful name. FFTabs are read by AGTC as .txt files.
