Abstract : An open-sleeve cross dipole antenna contained within a 21.5 in. square x 6 in. deep cavity is described for operation in the 240 to 400 MHz band. The antenna was developed for an aircraft flight test evaluation using a satellite-to-air communication link. For the purposes of these flight tests on a KC-135 aircraft the antenna was externally mounted to the fuselage and covered with a radome. Measured VSWR, radiation patterns and gain with the antenna mounted on a 9.5 ft x 9.5 ft cylindrically curbed ground plane are shown.
