Its probably not rain. Its probably condensation!
This will ALWAYS happen unless it is hermetically sealed and that is near impossible. DUring the day, hot moist air stabilizes inside and outside. At night the cooler temperatures will cause the mostirue inside to condense. Every day the cycle continunes. Water builds up to failured.
And that is why such things are placed in at least mildly tmperature controlled environments. Also, do not foget that night-sky radiative cooling of anything that can see the sky will cool below ambient and make condensation even worse.

Not a bad Idea, Paul. Although some duct tape on the bottom of the jug should keep out any further moisture. Also a bit of spray paint on the jug as well wouldn't hurt to protect from UV damage. That thin plastic wouldn't last long on its own.

None of the commercially made duplexers that I know of are made for outdoor service. Use the top half of a milk jug, run the cable through the top and seal off the top of the jug. Put the duplexer inside. using the top half of the jug as a rain shield.
That should keep 95% of the rain out of the duplexer.

I'm trying to setup a remote sat station and need help with a desence filter. I was using a Diamond MX72-n and was experiencing water
intrusion.
I then checked the archives and consulted the group and went to the recommended Comet CF-416. Guess what, I'm still getting water into the duplexer. I thought that it was more suited to outdoor service on the recommendation of the group. So, before I take apart one of the
duplexers to
attempt to waterproof, does anyone know of a duplexer that is designed
for
outdoor use on the tower? I really don't have the room for a 12 foot + crossboom, so I need to resolve the desence with the duplexer. Any suggestions from someone who has solved this?
