The need for unconventional types of very low frequency antenna systems as alternatives to the costly conventional systems is discussed. Possibilities of using very high vertical radiators of various structural types are explored. The loads and forces that must be sustained by 3000-ft high structures are described. materials suitable for unusual structural concepts are set forth. Concepts encompassing 3000-ft high guyed towers, compression-tension towers, free-standing towers, mass structures, and retractable towers are briefly analyzed and structural, erection, and economic feasibilities of the various concepts are presented. It was concluded that 3000-ft high vertical radiators could probably be built and maintained at lesser cost than the best conventional systems which require great quantities of radiating wires supported aloft by many intermediate height towers emplaced over large expanses of ground. Much detailed study would have to be performed to define and elucidate the structural, erection, and economic factors relating to any specific 3000-ft high tower structure intended for a particular site.
