I’ve been putting dielectric grease inside the RJ45 before I terminate it on tower sites for a couple of years now.
Cured my water problem with the electricals. I nicked the outer insulator on one of them at the lowest point, let out about a quart of water.

I've really got no ideas at this point - it's happened with every manufacturer and on different sites. No pattern to it (yet, hopefully...) Those do look really nice - I like the idea of 3 cables per grommit and it would simply be RJ45 again (as opposed to rj45ecs).

I like these which take 3 shielded cables in one gland: http://www.alliedelec.com/lapp-usa-53621380/70233572/ use to replace the bushing in any of their NPT-3/4 or PG21 glands, like: http://www.alliedelec.com/lapp-usa-s2134/70123709/ don’t forget locknuts: http://www.alliedelec.com/lapp-usa-911372/70123717/ If you have trouble with water coming down the cable, first thing is to find where it is getting in and fix that. But you can do a drip loop and ring cut the jacket inside the box at a point where the water can drip out and not cause problems. Or at one site I bought some 1 ft shielded jumpers and some shielded inline couplers just in case. (I was stupid and assembled the box with a rack that had all the electronics facing straight up.)

Going straight to RJ45ecs is a mess and going straight to the SS wouldn't be very cable management friendly and potentially ruin SS every time water finds it's way in, causing more problems.

I have a bunch of APs, BHs, cameras, etc on the tower with cat5/rj45. Those come down the tower. What do you terminate to? How do you organize them? I prefer terminating to rj45 and not a punch block, but maybe that would be better if the general consensus goes that way. My problem now is that going into an rj45ecs is nearly impossible to open up when you can't get your fingers around all of it, so when there are many tightly done together you're screwed.
