[amsat-bb] Poloarization Loss

2012-11-17 Thread Al Ozias
For line of sight communications where can I look up the signal loss due to polarization difference for a given receiving antenna polarization facing a transmitting antenna with a known different polarization? Al-N7EQF ___ Sent via AMSAT-BB@amsat.org.

Theoretically, the loss between vertical and horizontal polarization is infinite.  However, in the real world, 20 dB is the generally accepted figure.  In specific cases, the loss can be at least 30 dB and occasionally greater. Where circular polarization is concerned the same theoretical
