Panel went offline at 3am in a condo building in Austin and I found out the hard way the cellular module had a bad antenna connection
I was on site for 2 hours before I realized the SIM card was seated fine but the antenna pigtail had corroded inside the conduit, has anyone else dealt with moisture damage in outdoor cellular alarm panels?

Squeezed dielectric grease into the antenna connection and wrapped the whole pigtail in self-fusing silicone tape before it went back into the conduit... that stopped the corrosion for me. Make sure the tape overlaps itself by half an inch each wrap, otherwise moisture still finds its way in through the seams.
