Sk-35
Don’t order online yourself. Older designs are different before 2016 and will not work. Winegard won’t pay shipping if you get the wrong one and they don’t tell you that online. Before 2016 there is no replacement without ordering a whole new arm. Very bad customer service since ordering the wrong part is so easy and the website doesn’t inform you or tell you to call them first when ordering a replacement. Yes I am very unhappy.
