All,

I am experimenting with 4nec2 and these are an elementary questions. I have been
able to create a 'new' model, see below, using the geometry editor. Here are few
questions:

1. when the model loads it shows 4 MHz instead of 144.

2. ground has been set but does not show in the display

3. I am trying to make the middle segment a coil. How is a coil created? When
inserting a helix 4nec2 errors with a divide by zero error? The steps would be
helpful.

4. Adding a source does not seem to take. I am not sure how how to add a source?
How to determine where it is placed?

These are basic, but any help would be appreciated.

Thanks - Dan
