They are most often associated with portable radio systems, usually with pre-World War I field equipment, and were also occasionally used to increase radio range on Naval ships. The use of kite supported antennae was limited because of difficulty in maintaining consistent antenna height, unpredictability of the wind, and improvements in radio antenna, transmission, and reception. During World War II and after they were used in conjunction with survival radios issued to aircraft flying over-water missions.
