Hi, can you tell me difference between XPI - Cross-polar Isolation and XPD - Cross-polar Discrimination ? Exactly, how can I measurement it?


Thank!
 

Waiting question same you
 

XPD, Cross Polarization Discrimination, in wave transmission: ratio of the co-polarized average received power to the cross-polarized average received power.
XPI, if you feed in H, the received V vs. Input H.

Thanks tony_lth;
I have one question. what is the XPL. ? it similar the XPI. ?
 

Thank, so XPI is isolation between two connector on the same duplex antenna?
 

I am not antenna expert. I guess XPI is similiar to SNR, that is sensitivity of one antenna.
