.TH jiffy-perl-tk 1 "" "" "W5GFE ANTENNA TOOLKIT"

.SH NAME

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

.SH SYNOPSIS

  necview

  azimuth  [filename]

  elevation [filename]

  wiresview

.SH 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.

.B 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.

.B Elevation
provides similar information for vertical radiation 
patterns.

.B 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".

.B Necview
borrows heavily from the "xnecview" program by
P.T. de Boer (pa3fwm@amsat.org).  
.B 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 
.B W5GFE Antenna Toolkit
is released
under terms of the GNU Public License.
