Abstract

This report describes the tri-band receiving system for the 13.2-m antenna. Block diagrams and construction details are given. The measuring method for the noise temperature is described, and calculations and measurement results are compared. For the receiver feed, the results of the power pattern calculations and the measurements are presented.
