I had trouble getting the antenna mast out also. I removed the *** metal piece and this didnt help. I had to loosen the screw that is basically clamping the tube in place and remove one beside it that was locking the tube in place. After that the broken mast slid right out. Make sure you pay attention to the orientation of the tube when you remove it. Needs to go back in the same rotation. I also had to remove the black plastic cover to remove a large section of broken gear. Almost didnt see it as it was a bit deep. After 8 years the antenna works as designed. Very happy
