Abstract:

This engineering study has resulted in the generation of efficient antenna techniques consistent with the capabilities to withstand the effects of nuclear weapons. The HF antenna techniques considered in this study are useful throughout the 2-30 mc frequency band the UHF antennas operate in the 225-400 mc region. The program was divided into two phases. Phase I was a theoretical study of antenna techniques which were investigated with regard to feasibility, configuration required, bandwidth possibilities, efficiency, radiation patterns, hardness ratings, debris effects, and economic analysis. Phase II involved the fabrication and test of electrical models of the most promising designs. This phase resulted in design data, cost and hardness estimates for antennas for the HF and UHF bands.
