Earth Stations In Smaller Packages (1977)
By Carl Van Hecke, Andrew Corporation
Why are small aperture earth stations so popular? - economics and ease of location. What can a small aperture earth station provide to the cable operator? This paper will analyze the performance of earth stations employing antennas with diameters smaller than 9-metre, with emphasis on the 4.5-metre size. Impact of adjacent satellite and terrestrial interference to these smaller antennas and the effect on system G/T is discussed. Economic trade-offs between antenna and low noise amplifier are presented. Carrier-to-noise ratio of the system as it relates to receiver threshold is also discussed.
