Unfortunately, the real world is far more complicated that this. What 
you describe can work for local sources, but propagated sources can take 
different paths, each introducing delays that can, for example, cause 
cancellation of multiple arrrivals at on antenna while reinforcing at 
the other. THIS is what causes selective fading, and is why diversity 
works! In other words, it's FAR more than one vertical antenna and one 
horizontal one.
