Add to ORKGThe invention to be hereinafter described relates to coupling devices for the attaching of fixed wire antenna to aircraft. Heretofore, it has been the general practice to make connections between the fixed wire antenna and aircraft by wrapping the antenna wire about a thimble or like device, as in making a splice. This practice resulted in a number of sharp points and rough surfaces whose susceptibility to corona discharge is well known. This corona discharge resulted in bad weather extremely difficult or dangerous due to interruption of radio navigation and communication services. The present invention is designed to overcome the above and other objections and to provide a simple, compact, efficient, durable and readily manufactured coupl...
