This complete kit that allows you to install a Windex 15" vane to any Shakespear, Metz or other brand whip antenna. Sailors have been doing this installation themselves for many years by taking apart a standard Windex 15" vane and installing the parts onto these kinds of antennas. The Windex AV is a much more economical way of doing this. Comes with Teflon® bearing washers, adjustable stainless tacking arms and reflectors underneath the tabs and wind vane. Reduce masthead clutter by combining two installations into one!
