NAME

  W5GFE Antenna Toolkit  - a Perl Toolkit for analysis of NEC2 files

SYNOPSIS

  Necview

  Azimuth  [filename]

  Elevation [filename]

  Wires

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.

Wires 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 each subdirectory.

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