I know the magnets come with a felt on the bottom so I don't see them scratcing, I belive it is a pretty strong magnet so I don't see it moving. Only thing I can think is the fact that it is soo damn high, and would hit everything. I like this

The antenna shown here is my Wilson Flex 3' CB top loaded antenna mounted on the factory antenna mast:
The SWR is as low as I can get it, 1.5:1, the reception is excellent and I'm getting good transmission range. I'm thinking about getting the 4' Wilson Flex but I'm not sure how garage compatible that will be because I don't want to put too much stress on the factory mast mount every day, but the antenna easily bends 180 degrees.
I think it is kick-ass having the CB mounted up there. It is easy access, out of the way and very easy to use on and off the trail. The mic is on a retractable cable and I can wedge a mic clip between the console and roof liner to secure it if I wanted to."
however I already have some 3' firefly antennas and will work with them.
