I think the problem with rain is not the effect on the direct signal, 
which is negligible as your calculation showed, but the effect of 

Is a rain cloud is nearby, it could reflect signals with significant 
strength, causing multiple receptions at your location, with signals 
that may have traveled many more miles than the main signal.
