 Jeff,
There is some information on page 2-18 in the ARRL YAGI Antenna Classics publication.
Hope this helps

 Good Afternoon...
  I am rebuilding a HyGain 204-BA, 4 element 20 meter yagi. This antenna 
is 45 years old. It originally came out some time before 45 years ago, 
so the design is old. There were some mods which came out years ago, 
after computer modeling became fashionable, for better element spacing 
and length. In researching the internet, I have found 3 different sets 
of measurements. So, I don't know which is best..
  By chance, has anyone any experience with optimizing a 204-BA? Do you 
have any recommended measurements? Do you have any Eznec EZ files?
  Thanks for any help...

73,
Jeff - K5WE
