HIGH-TEMPERATURE ANTENNA INVESTIGATION AND DEVELOPMENT

Abstract

This quarterly report summarizes investigations which were made for developing antennas suitable for prolonged operation at a temperature of 2000F. The efficiencies of S-band helical antennas made of various metals were compared and no significant reduction in efficiency occurred with metals having resistivities as high as 120 microhm - cm. Tests made on nichrome and coated tantalum helical antennas at 2000F showed no degradation with temperature. Experimental tests for determining the relative power handling capabilities of copper, TD nickel, coated tantalum and Boride Z metals at 2000F are being made. (Author)
