[amsat-bb] Re: LHCP or RHCP?

[Tom]

Perhaps I should have worded my question differently. I understand the
concept of circular polarization and the reasons for it. What I should have
asked was "Is one direction preferred over the other for working the
satellites?". Thanks for all the excellent info and I think what I've
learned is that the ability to switch between directions of polarization is
best but RHCP is preferred if only one direction is available. 

Domenico, thanks for the attachments. Good stuff which I had not seen
before!
