The antenna is stuck part way up. The ball at the top of the antenna somehow just vanished from the mast so the operation is must up. Right now, it is part way up but the top of the mast fell down into the other larger parts at the bottom so I can't get to it. I think it still operates properly but i just have to get to the tip of it and put the ball back on. Any ideas? thanks
