I hear ya Kurt. Not sure about the 900mhz part.
In my mind the problem isn't only the moisture, it's also the corrosion that comes with it. 900 handles water better than 2.4 or 5 gig does, very true. But a corroded connector isn't going to work as well as a clean one. And it's not like the old VHF days when we had tens or hundreds of watts to play with and only voice, that no one expected to sound perfectly, to transport. Me? I just don't buy devices that I can't weather seal. I tell manufactures that all of the time. I don't care if you can give me a $5.00 radio that will deliver 200mbps to home users at 50 miles on the other side of a mountain, if I can't make it reliable I just can't use it these days. Internet is no longer a toy used for sending the occasional email and downloading one's favorite songs. I've tried silicone in a situation like that but there is something inside it that will actually speed up the corrosion inside the connector. So far the best thing I've found is to take the offending device to a machine shop and modify it. And/or use jumpers so you've got more room to work with.
