COWs (Cellsites On Wheels) come in MANY different configs. Often the 
purpose of the guys is to prevent overturning (for lack of outrigger 
footprint), in which case guying just the  bottom section is all you need.

That said, it's amazing how little engineering direction comes with the 
installs. It's a seat-of-the pants operation, kinda like Field Day!
