Thanks ARMYbrat. This USMCbrat appreciates it, and everything else! 
Most of what I've found thus far is about the same as what we're currently
using, which is a flat 4 element Yagi. I may not be versed enough to
describe the plans I'm looking for, but when I find them I'll post here.
The antenna I'm looking for is perhaps better described as a 4 element Box
or Cube Yagi where the frame is built of 1/2 inch PCV and the elements are
fairly heavy guage wire. There's no sharp points to hurt someone's eye,
which is frowned upon by the California Highway Patrol for use in their
helicopters. There's a guy that I trained with who has the plans and
hasn't yet gotten back to me with them, but I'll be persistent and let
people here know when I get the plans.
Search Google with "cubical quad" and you'll find what you want, I think.
There are even some calculators for this type antenna listed.
