I got a bunch of replies from the group. I thank you all for that. As there doesn't appear to be a weatherproof duplexer available I ended up taking the duplexer apart then sealing all openings airtight with silicone leaving a small hole on the bottom side, the dual lead side. Several suggested some kind of enclosure I didn't want to go that route as it would just make another home for the local flying critters. I was also told that it wasn't water but condensation, I don't think so as both duplexers were completely full of water, you would think both ends would pass water equally but it appears that the connector end as opposed to the lead end is the culprit as the water would get in but then not drain out Another interesting comment was that there is no weatherproof amateur radio equipment suitable to leave outdoors, my Landwehr preamps have been outdoors in the open for over 18 years and their doing fine. When I recently moved them to my new QTH all the markings on them were gone, I had to open one up to positively identify the 2m vs 70cm one. Inside was dry as a bone and no corrosion or rust. :-)
Still looking for someone who has successfully got full duplex remote sat ops working.......

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?
