I’ve decided to try and waterproof the electrical box. I have a waterproof ethernet pass through jack and a waterproof USB mini panel mount on the way. It looks like no one makes a waterproof rca jack anymore, and I have to pot the rivet mount points anyways (no idea how I’m getting those out) so my plan is to add a thin epoxy retention slide in divider internally, and extend the top face up and pot the balun in place at the same time. That, coupled with a large groove for rtv silicone gasket material should waterproof most of the case . A replacement cover for the reel side and more gasket material there should take care of most of that, and some potting in the reel cable gland will finish that off. I may add a seacon cable disconnect at that end as well, not because it really needs it, but I’d I have seacon ends on both ends, I can theoretically join two sections later when I can afford another segment. Next I just need a cable segment longer than 3 feet!
