NAME
yagi - Yagi-Uda project antenna current calculator
SYNOPSIS
yagi [ - dhps ] filename
DESCRIPTION
The program yagi is one of a number of executable programs that forms part of a set of
programs, collectively known as the Yagi-Uda project , which were designed for analysis
and optimisation of Yagi-Uda antennas. yagi calculates the currents at the centre of each
element at one or more frequencies, as specified in the input file.
AVAILABILITY
OPTIONS
-d Display element currents. When this option is used, a bar graph with up to 70 stars
(*) is used to display the absolute magnitude of the element currents. The element
with the greatest element current has 70 *'s, all others have a corresponding
smaller number, depending on the their relative current. The element current,
normallised to the maximum, is also shown as a 4 digit floating point number.
-h Print a help message.
-p Print the Z matrix. The Z matrix is the impedance matrix, showing the self
impedance of the elements on the diagonal and the mutual impedance off the
diagonal.
-s Suppress all diagnostic output. By default, the program print the percentage of the
job completed.
filename
is the name of the file containing the antenna description. It is expected to be in
a format created by either input or first - two other programs in the Yagi-Uda
project. This is an ASCII text file. The antenna currents are written to a file
filename.out which is a binary file. It is not intended to be read by humans.
Limitations
I'm not aware of any limitations, apart from that filenames, including full path, can't
exceed 90 characters.
