YAGI(5) File Formats Manual YAGI(5) NAME
yagi - yagi binary output format DESCRIPTION
This manual page describes the output format of the file created by the Yagi-Uda project's yagi program. The file is a binary file with a header of 100 bytes. The header consists of: offset(bytes) information data-type 0 elements int 4 driven int 8 parasitic int 12 min_frequency double 20 max_frequency double 28 design frequency double 36 step_frequency double 44 angular_step double 52 0 double 92 0 double Following the header, there starts the coordinates(x,y,l) of each element and the voltage applied to each element. Then we write the element currents one after the other, at each frequency. Hence the element currents will be written 12,000 times with a 3 element yagi analysed at 4,000 different frequencies. All complex data is stored in a structure of type fcomplex, defined as: struct fcomplex {double real, double imaginary}; offset(bytes) information data-type 100 x1 double /* coordinates */ 108 y1 double 116 l1 double 100+(n-1)*24 x_n double 100+(n-1)*24+8 y_n double 100+(n-1)*24+16 l_n double -------------- Repeated for each element. 100+24*elements Voltage1 fcomplex /* voltage */ 100+24*elements+(n-1)*16 Voltage_n fcomplex -------------- Repeated for each element n at each frequency step f. 100+40*elements Current1@f1 fcomplex /* current */ 100+40*elements+(n-1)*16 Current_n@f1 fcomplex 100+56*elements Current@f2 fcomplex 100+40*elements+(n-1)*16 Current_n@f2 fcomplex FILES

input - Yagi-Uda project antenna defining program SYNOPSIS
input [ - h ] DESCRIPTION
The program input 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. input is an interactive program, that asks the user for information about a Yagi design, such as position of elements, spacing between elements, frequency span of interest and a filename to save the data to. input then writes this information into an ASCII file, which can be read by yagi or optimise The file is ASCII and it's for- mat is easily understood by inspection (there are comments printed in it), so it can if necessary be edited manually. After running input and specifying a filename (for example 144e10) you should then type yagi 144e10 and then output 144e10 and optionally optimise 144e10 OPTIONS

Both DOS and Unix versions have been built. The DOS version as distributed requires a 386 PC with a 387 maths coprocessor. AUTHORS

Bugs tend actually to be fixed if they can be isolated, so it is in your interest to report them in such a way that they can be easily reproduced. If a mistake is made during inputting of data (such as entering an incorrect length), it is not possible to go back and correct this. You should make a note of the error, and edit the ASCII text file with a text editor (vi, DOS edit etc). Version 1.16 24th October 2000 INPUT(1)
