We do this in several products we supply to the military.
Does this help significantly for an antenna preamp that doesn't dissipate much power? How much power does a board have to dissipate to keep dry? I assume it depends upon the size of the board, but I doubt if it's linear. What's magic about vertical for keeping dry? I'd expect a vertical board to have better air flow and hence better cooling, but does that keep it dryer? -- These are my opinions.
