Radio equipment for propagation experiments at the frequencies 11, 18, and 36 GHz
Abstract
A program which tests the suitability of frequencies above 10 GHz for telecommunications is described. Atmospheric and climatic effects are studied. Output is unmodulated CW on seven frequencies, received simultaneously at one site. In 4 cases the intensities of the horizontally and vertically polarized components are recorded separately, giving 11 receiver channels. One single and one dual polarization antenna are used. The tests run for three years. No permanent damage should result from operation at ambient indoor temperatures 50 C; 100% humidity; and AC voltage variation from 0% to 120% of nominal. No results are available.
