I just finished installing my Uniden CB radio with a 3' Firestick antenna. I used the antenna mount that goes behind the tail light on the drivers side. After getting it all done, it sure seems like the antenna has a lot of "leverage" on the mount and that it's really easy to flex the sheet metal of the tub by moving the antenna (antenna has a base spring). I'm just wondering if anyone has had any trouble with cracking of the tub metal by the tail light after using this antenna mount? Thanks.
