Greg, My two cents is that AO-51 seems to be very sensitive on the L band receive, so a decent antenna will get in fine. I have been using RHCP on my uplink, a 31 turn homebrew helix modeled after the VE3NPC, and I have not experienced any fading problems on uplink. My choice then is to opt for the circular polarization. I do feed mine directly at the antenna (about 5 feet of LMR-400 from the upconverter) but I think your helix with the power you are feeding it is probably quite capable and a better idea to avoid the fading.
