If you are not going to use guys, you need to bury the base section.  But if 
you do use guys, it would be sturdier to use the base plate, to allow the 
tower to sway and twist at the base during strong windstorms.  That would 
relieve stress on the tower structure that would otherwise result from a 
base section rigidly mounted in concrete.  That's why most large guyed 
towers use a base plate and pier pin.
