[amsat-bb] Loss Between Right and Left Circular

[Roger Cooper]

About 10 years ago got interested in sat radio and bought a Left Circular
Quadrifilar Helix Antenna which got good review in QST.  Didnt use it and
now retired and trying to get on sat. Evidently most ham sats are right
circular and depending on
what I read. there is a 30db OR 3db loss going from one circular
polarization to another. Which is it?
