Yagi Scale

The whole point of this is to help people adapt yagi type antennas
to their preferred construction materials.

This suite will allow scaling of frequency, or of element diameter.

brief description of programs, in the order you might want to use them:

scin:
  allows you to enter antenna data (frequency, number of elements, element
  lengths/diameters).  Nice, sweet, easy.  Prompts for everything.
  usage: scin <outfile>

fsc:
  allows you to scale an antenna to a new design frequency
  usage: fsc <infile> <outfile> <new frequency>

dsc:
  allows you to scale an antenna to a different element diameter.
  It does NOT allow you to scale elements to different diameters.
  usage: dsc <infile> <outfile> <new diameter>

tofrac:
  People who deal in imperial units (inches and stuff), generally
  also work in fraction rather than decimal, as that's what most of the
  measuring tools are marked in.  This will take a data file and output
  it to fractional approximations, as might be suitable to print out
  and try to build an antenna from.
  usage: tofrac <infile> <outfile>
   NOTE: the outfile from this program cannot be used as an input file
         for any of the other programs in this suite.




read:
  this isn't really a program.  This is a shell of a program that reads
  a file and writes it out.
  You might want to use this if you wanted to write your own scaling (or
  other) program. 
  usage: read <infile> <outfile>

Future Enhancements:
  hopefully, a program to read and/or write files to David Kirkby's
  Yagi-Uda package.
