While doing post snowbirding cleaning, I noticed the rubber weather boot had slipped off on the roof feed through for the Sensar antenna's coax lead-in. I tried to reattach it, but it kept slipping off, even with a small hose clamp. They must have used some kind of adhesive to attach the rubber boot to the metal nipple, but what kind? Anyone have any ideas? My roof is of rubber membrane construction.
Any help would be appreciated!
