The satellite and ground based antenna reflectivity investigations have been made. It was revealed that the reflective coverings of some composite carbon fibers antennas have inadmissibly more reflective losses which lead to the essential noise temperature increasing of high sensitive cooled receivers. The significant anisotropy of carbon fibres antenna covering have been found. Unexpected reflectivity behaviour of satellite antenna reflectors at liquid nitrogen temperatures was found.References
