In a nutshell/ my conclusion/ advice on the RHCP/LHCP issue: to operate the birds for HAM purpose the simplest way is just to have polarization relays on both uplink and downlink antennas, then manually switch polarization as required depending on the fading, which has quite different patterns depending on the bird and their trajectory, after some time an practice it becomes natural and you push the button without even thinking. I do so all the time during Sat. passes.
I think this is the best advice... :)

p.s. All this said in the thread, I am a still bit confused. I thought circular polarization was like nuts & bolts. You can thread the nut on a bolt with either piece in either direction; the thread on them doesn't change just because you picked it up "backwards." I can see the possibility of a reverse polarization in the side lobes, but out the back of the antenna shouldn't it be the same as the main lobe? Or am I nuts (pun intended)?
