MECHANICAL DESIGN AND DEVELOPMENT OF LIGHTWEIGHT ANTENNA REFLECTORS AND POSITIONING DEVICES. PART 2. DESIGN AND DEVELOPMENT OF LIGHTWEIGHT ANTENNA REFLECTORS
Abstract
Two lightweight reflectors were designed and developed to meet the operational needs of the Signal Corps. One is a low-cost, rigid-foam reflector, with a feed system foamed into position. Experimental models of this type reflector were tested on the antenna range against metallic reflectors for comparison of performance at frequencies from 8.5 to 11.5 gc. The results show that the 2 reflectors are very comparable for surface accuracy and gain characteristics. Complete scale models of rigidfoam reflectors will be built and tested for mechanical, electrical, and thermal properties. This reflector can be more easily fabricated than present designs; since the only precise dimension is the reflective surface, it requires no special fixtures and only simple cutting tools. The fabrication process is facilitated by a specially designed field portable Foam Shaping Machine (FOSHAM). The other type reflector is a folding, portable reflector, light enough to be hand-carried, and capable of being erected quickly and efficiently for military tactics on any terrain. (Author)
