Aerials. - An aerial of the type comprising two circular frames a, b mounted mutually at rightangles to support a spherical winding is characterized by the provision of insulated staples g fixed to the outer edges of the frames and arranged parallel to and equidistant from each other. The aerial winding starts from a hook e near the base-support, passes through an insulated tube f at the upper crossing-point, and is then threaded through the insulated staples as shown. The diameter of the spherical aerial so formed may vary from six inches to six yards.
