For example, a three element beam looks like this:. Right now this antenna is laying on the ground! The Z-axis is the height of the antenna above ground. Working this way allows you to concentrate on drawing the antenna in two dimensions, then by adding in the antenna height in the Z-axis, the antenna will move up in height.

To raise the height of the antenna, click on a wire, then in the Wire data section, add the height to the Z-axis; the Z-axis is the highlighted text boxes. Remember you have to add height to the Z-axis for both ends of the antenna and the values are always positive. Putting a negative value for the Z-axis will place the antenna underground! Click on the button, the antenna will no longer be on the ground.

We can call that 33 feet for this demonstration. Plus, the ground underneath the antenna will also come into play so the length derived from the equation could be slightly shorter or longer. When the dipole is installed at the length of the standard equation determine the SWR at resonance.

For example, resonance happens to be Slightly higher than calculated. Do the calculation one more time using the new constant to determine the new length and the new dipole will be resonant at the design frequency. Anyway, back to using 4NEC2! To draw the antenna in the Geometry Editor, click on the toolbar button, on the right, use the Zoom slider to make each grid square 1 foot long, then enter the design frequency in the Frequency textbox.

Now that the Geometry Editor is configured, click on the button then draw a line as evenly as possible along the Y-axis with half the wire on the negative Y-axis, and the other half on the positive Y-axis. Click OK on the Wire Radius dialog box. We need 33 feet so enter. The dipole is one long segment, that needs to be changed as well. Enter the following into their respective textboxes:.

Remember the Z-axis is for height above ground so enter 33 into both End-1 and End-2 text boxes. Take a look around your location to see what the ground looks like. To choose which ground to use, click on the on the toolbar and the Ground Parameters pane will appear. Select Real Ground from the drop-down, then from the lower drop-down, select Dry, Sandy, Coastal or your own ground type if you prefer.

The settings look like this:. The source will be placed right in the center of the antenna, which would be segment 6. By placing the RF source on segment 6, that leaves 5 segments on either side of the source. To add a source, click on the then buttons. Click the button, move the cursor on the grid and it will change to dark cross hairs.

Hold down the left mouse button and drag the source to the center of the dipole coordinates 0,0. The Geometry Editor will look like this:. The source is the circle centered on the origin.

Sources will always be placed in the middle of a segment. The very light gray rectangle represents that there is a ground underneath the dipole. Click on the button to see the final creation! Click on the button on the far right side of the Geometry Editor; the Generate window will be displayed.

Select Far Field. What do the results look like? The Main Window gives us the electrical details of our dipole at a half wavelength above ground. We know the feedpoint impedance, S. What would the vertical gain look like at different heights? After calculation:. Great for local communications but not so much for chasing DX. What does that look like? Now the pattern really changes!
