Antenna concerns

This is my first winter with this Jayco 26xd. I put the winter cover on today and after getting it all nice and snugged up I went up the ladder to check things out and I noticed it is really putting a lot of downward pressure on the King Jack TV antenna. The antenna that looks like a mushroom. Has anyone had any problems with this antenna breaking or causing roof damage after snow piles up on the roof/cover?
My last RV had a crank down antenna so this wasn't an issue.
