In this paper, the QZ cross-polar reduction properties of the  CXR  feed  is  measured  in  a standard  corner-fed  CATR  in both orthogonal polarization over the full 1.6:1 bandwidth. The advantages of the CXR  in  general measurement  scenarios  are investigated  by measurement  of  an  antenna  with  low  cross-polarization level at different QZ positions and frequencies. It is shown that a cross-polar discrimination improvement up to 10dB is achievable.
