DEVELOPMENT OF AN IMPROVED CENTER-FED WHIP ANTENNA.

摘要

The purpose,principles of operation,design objectives,and performance of the improved center-fed antenna are reported. Detailed data are given for both the vehicular model and the elevated model which is designed for mast mounting to achieve increased communications range. The vehicular model has been reduced 50percent in weight compared to its predecessor and its reliability and economy of manufacture has been substantially improved by reduction in the number of components. The elevated antenna weighs 9.4pounds,including counterpoise,and yields 3to 4db greater gain than the RC-292antenna under the same conditions of operation. The improved antenna meets all the major design objectives and one model has been subjected to a set of stringent environmental tests with very good results. (Author)
