Nec2Go Product Features

Input fields are marked in blue as a hint that they can be modified. Nec2Go only requires the VB6 runtime Dll(MSVBVM60.dll). If this is not on your system, you can find it on our downloads page.

Help Information:  Moving the cursor over any field or label will produce a short help pop-up window description. Pressing F1 will present Context Sensitive Help. However, If you are new to Nec modeling, please read the 'Beginners Tutorial' entry in the Help file. This will explain some of the terminology and assist with understanding the internals of Nec processing. Please use the Help file when in doubt.

• Minimum number of screens required during process. Main, Edit, View, 2d-plot, and 3d-plot screens plus Tools and Help.
• Run output, SWR, Gain and Sweep results on Main screen.
• Text input for all antenna models using algebraic statements.
• Geometry functions SIN, COS, and SQR. Shift and Rotate functions applied to wire definitions.
• Automatic Segment generation.

• Context Sensitive Help for all screens and controls.

Context Sensitive Help has been implemented. Place the cursor over a control or output area and press F1.
A Help screen is presented describing that function. In Edit, position the cursor in the text and press F1 for Help on the current statement.
