Hello Wayne.
I found the program I used to model the TV LPDA that I made.  I don't recall 
or have the plans that I made it with, but as the owner of a machine shop, I 
dont' have a problem making what I need.
From memory, the boom spacing (1/2"dia alum) was about 1.25" or so.  The 
overall length is around 4'.
