Sun has a way of coming in and yellowing these handles, and then they get brittle. I've had a couple snap on me when I try to move the antenna. While Winegard has a lubrication procedure for the antenna base on the roof, almost no one does it, so they are usually a bit stiff too. Don't be surprised if you need to replace the handle, but good news is they are very common and probably easy to find.
