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.
