Subject:	NSA/KAZR/C1 - Polarizer rotated
DataStreams:	nsakazrciC1.b1, nsakazrgeC1.b1, nsakazr3253C1.a0
Description:	The cross-polarization returns were higher than the co-polarization returns causing a positive linear depolarization ration. This cannot be correct. Upon further investigation, it was suggested that waveguide going to the antenna feed polarizer was possibly rotated by 45 degrees resulting in the antenna transmitting circular polarization rather than linear polarization. Rotating the polarizer in June did not correct the problem. It turns out that there is a polarizer in the antenna feed. Rotated the OMT by 45 degrees and substituted micro-coax cable instead of waveguide. During the time covered by this DQR, the "co-polarization" variables are circularly polarized opposite of the transmitted polarization. The "cross-polarization" variables are the same circular polarization as the transmitted signal.
