How does satellite TV get through in rain?
According to this paper I found, http://licensing.fcc.gov/licensing.fcc.gov › myibfs › download, there is 3 dB loss allocated for rainfall in the downink direction for Ku band.  That's not very much compared to all the other losses in the link budget.  The fact that you don't see dropouts during rain just means that there is adequate margin to cover rainfall loss.
