# jiffy-perl-tk(1)

a Perl-TK Toolkit for analysis of NEC2 files

## NAME

  Jiffy-perl-tk - a Perl-TK Toolkit for analysis of NEC2 files

## SYNOPSIS

  necview

  azimuth  \[filename\]

  elevation \[filename\]

  wiresview

## DESCRIPTION

These programs are written in Perl/Tk (version 5.005\_2), and provide tools which can help to visualize antennas or analyze data which is produced by NEC2 - the antenna modeling program.

The NEC2 program is commonly used by radio amateurs or professional antenna designers on Unix equipment to model antennas.  While NEC2 is quite versatile, the output of  NEC2 is voluminous and difficult to read.  This suite of programs  provides graphical depictions of NEC2 output.

**Azimuth** provides three graphs of "horizontal" radiation patterns:  an ARRL-scaled polar plot, a linearly scaled polar plot, and a cartesian plot.  A "fact box" provides indication of -3 DB beam widths.

**Elevation** provides similar information for vertical radiation  patterns.

**Wiresview** is a visualization tool which shows three views of the same antenna.  Views are provided for the "XY plane", the "YZ plane" and the "XZ plane".

**Necview** borrows heavily from the "xnecview" program by P.T. de Boer (pa3fwm@amsat.org).   **Necview** provides an animated view of an antenna which can be "rotated" in three dimensions to  provide different viewpoints.

Sample data files are included in the examples subdirectory.

The  **W5GFE Antenna Toolkit** is released under terms of the GNU Public License.
