The Windows ® program for analyzing vertical antennas

This program shows the resistance and reactance to be expected looking into the base of a cylindrical metallic tower over a perfect ground. It gives a useful approximation of the values to be expected in a real-world situation.

Here are the highlights of this program:
  • This program is a graphics type with plots of resistance (R), reactance (jX) and impedance (Z) presented simultaneously as a function of frequency.

  • Although most-precise for cylindrical antennas over an ideal ground plane, it has proven to be quite useful in "real world" situations as well.

  • Writes a comma-delimited file with frequency, resistance, reactance and impedance tabulated for input to another program.

  • High-resolution output to the printer as well as the screen
