N2 - Measurements have been made of the cosmic-background-radiation spectrum at five wavelengths (0.33, 0.9, 3, 6.3, and 12 cm) with use of radiometers with wavelength-scaled corrugated-horn antennas having very low sidelobes. A single large-mouth (0.7-m-diam) liquid-helium-cooled absolute reference load was used for all five radiometers. The results of the observations are consistent with previous measurements and represent a significant improvement in accuracy at low frequencies.
