Water-cooled coupler installed in S-band polarization diversity (SPD) cone is used to calibrate receiving-station relay. Coupler operates without arcing at 400 kw and permits accurate calibration of entire system below antenna feed horn. Device has good directivity, contributes less than 0.01 K to system noise temperature, and eliminates saturation of ground station and spacecraft receivers during high-power operation.
