NAME

       output - output data file formats

DESCRIPTION

       This  manual  page describes the output formats of the files created by the Yagi-Uda project's output program. The files are ASCII file, so
       can be analysed with any graph plotting program.

Example of a .dat File
       Below is a typical .dat file, for a 4ele 144-146MHz beam, optimised for a huge (and useless) FB.

       # Driven=1 parasitic=3 total-elements=4 design=145.000MHz
       # Checked from 144.000MHz to 146.000MHz.
       f(MHz) E(deg) H(deg) R	    jX	 VSWR  Gain(dBi)  FB(dB) SideLobes(dB)
       144.000 54.7  71.5  44.47  -2.35  1.136	9.386	  21.944     16.650
       144.500 54.0  70.1  41.34  -0.75  1.210	9.553	  27.244     17.153
       145.000 53.2  68.4  37.55   1.61  1.335	9.742	 103.055     17.777
       145.500 52.3  66.6  33.26   5.00  1.530	9.947	  25.734     18.547
       146.000 51.3  64.6  28.77   9.63  1.832 10.149	  18.919     18.919

What is what in the .dat file
       The f(MHz) column is the frequency (MHz) at which the data is evaluated at.
       The E(deg) column is the approximate 3dB E-plane bandwidth calculated to the nearest 0.1 degree.
       The H(deg) column is the approximate 3dB H-plane bandwidth calculated to the nearest 0.1 degree.
       The (R) column is the input resistance in Ohms.
       The (jX) column is the  input reactance in Ohms.
       The (VSWR) column is the input VSWR, usually refered to a 50 Ohm input, but this may be changed.
       The Gain (dBi) column is the gain at theta=90 degrees, which is the forward direction of the beam. It is possible that a higher gain occurs
       at other than 90 degrees, but this is not taken into account. The antenna is seriously at fault if this occurs.
       The FB(dB) column is the front to back ratio in dB.
       The  Sidelobes(dB) column is the minimum level in dB down from the peak gain of any sidelobe. This is not calculated unless the '-c' option
       is used, and then only on some optimisation techniques.

Example of a .gai File
       The following is a small section of the .gai file.
       f(MHz)	  theta  gain-E(dBi) G(E)-peak	 phi   gain-H(dBi) G(H)-peak
       144.0000 -90.0000  -12.5584   -21.9444 -180.0000 -12.5584  -21.9444
       144.0000 -45.0000   -7.3507   -16.7367 -135.0000  -3.5971  -12.9830
       144.0000   0.0000 -999.0000 -1008.3860  -90.0000  -0.9010  -10.2870
       144.0000  45.0000    0.1848    -9.2012  -45.0000   4.0261   -5.3599
       144.0000  90.0000    9.3860     0.0000	 0.0000   9.3860    0.0000
       144.0000 135.0000    0.1848    -9.2012	45.0000   4.0261   -5.3599
       144.0000 180.0000 -999.0000 -1008.3860	90.0000  -0.9010  -10.2870
       144.0000 225.0000   -7.3507   -16.7367  135.0000  -3.5971  -12.9830
       144.0000 270.0000  -12.5584   -21.9444  180.0000 -12.5584  -21.9444

What is what in the .gai file
       The f(MHz) column is the frequency in MHz.
       The theta column is the angle theta, for which the next two columns refer.
       The gain-E(dBi) is the gain at theta, relative to an isotropic radiator.  This is the E-plane gain. Hence at the peak (theta),  this  gives
       the peak forward gain.
       The G(E)-peak is the gain at theta, relative to the peak gain. Hence at the peak (theta=90 degrees), this is zero.
       The phi column has nothing to do with the previous 3 columns. It is the angle for which the next two columns refer.
       The gain-H(dBi) is the gain at phi, relative to an isotropic radiator.  This is the H-plane gain. Hence at the peak (phi=0), this gives the
       peak forward gain.
       The G(H)-peak is the gain at phi, relative to the peak gain. Hence at the peak (phi=0 degrees), this is zero.

Example of a .up File
       The .up file list the improvements made by optimise to an antenna design. Starting from the original design, the file is appended each time
       a  new  better  design is found. Here is an example, where the final line is the performance of the 4ele beam with the .dat file shown ear-
       lier.
	   1 7.57dBi,  16.93dB F/B, Z=(31.77-56.34j) Ohms, VSWR=3.95, SL=16.95 dB
	  84 7.58dBi,  16.93dB F/B, Z=(31.78-56.32j) Ohms, VSWR=3.95, SL=16.95 dB
	 623 7.58dBi,  16.93dB F/B, Z=(31.78-56.28j) Ohms, VSWR=3.95, SL=16.95 dB
       89345 9.74dBi, 103.06dB F/B, Z=(37.55 +1.61j) Ohms, VSWR=1.33, SL=17.78 dB

What is what in the .up file
       The first column is an integer specifying the iteration. The other columns, going from left to right are gain(dBi),  FB,  input	impedance,
       VSWR and level of the most significant sidelobe, in dB down on the peak gain.
