description: Many computational instruments have succumbed to the power of the digital computer. This is not the case with the Smith chart. A testament to Phil's genius is that his chart remains an important training tool and has evolved into a new role as a display grid on computer instrument screens. winSmith, a supplemental program to the book, is available form Noble Publishing.

  The Smith Chart is a sophisticated graphic tool for 
  solving transmission line problems. One of the simpler 
  applications is to determine the feed-point impedance of 
  an antenna, based on an impedance measurement at the 
  input of a random length of transmission line. By using 
  the Smith Chart, the impedance measurement can be made 
  with the antenna in place atop a tower or mast, and there 
  is no need to cut the line to an exact multiple of half wave-
  lengths. The Smith Chart may be used for other purposes, 
  too, such as the design of impedance-matching networks. 
  These matching networks can take on any of several 
  forms, such as L and pi networks, a stub matching sys-
  tem, a series-section match, and more. With a knowledge 
  of the Smith Chart, the amateur can eliminate much “cut 
  and try” work. 
  Named after its inventor, Phillip H. Smith, the Smith 
  Chart was originally described in Electronics for January 
  1939. Smith Charts may be obtained at most unive
