NAME

  Azimuth - a program to view azimuth patterns

SYNOPSIS

  Azimuth [NEC2outputfile]

DESCRIPTION

Azimuth reads files produced by NEC2 and provides three graphical depictions of
that data, as well as a ``fact sheet'' summary. The default NEC2outputfile is
``fort.2''.

The three ``plots'' of output data include an ARRL-scaled polar graph, a
linearly-scaled polar graph, and a cartesian graph of the same data.

If the minimum gain of an antenna is below -60 db, the program assumes a minimum
gain of -60 db for the purposes of scaling the graphs properly.

In order to use Azimuth you must have NEC2 calculate certain data. The ``RP
card'' for NEC2 input must be of this form:

RP  0  1    361 1001  75.0  0.0  0.0  1.0  10000.0 0.00E+00

This will insure that Azimuth has the data it expects.

A sample data file which describes a rhombic is included with Azimuth, and is
reproduced here also.

A NEC2outputfile that results from this input file is included in the Azimuth
distribution directory as "fort.2".  A file called "azimuthcard" is also
included.  That file contains only an appropriate "RP card".

Azimuth is part of the W5GFE Perl Antenna Toolkit.  It is released under terms
of the GNU Public License.
