You are talking about the two satellites I regularly access using a handheld radio at about 2.5W and either an Arrow dual-band antenna or simply a longer duck.
In my experiences, orienting the Arrow 90 degrees in either direction gives no discernable improvement on the RX signal: It's clear and wonderful no matter how I twist the Arrow.
Do the concepts os LHCP and RHCP come into play when you are trying to access lower elevation passes? AO-51 and SO-50 are so darned easy to hit with minimal equipment...and there is certainly NO "large difference between using RHCP and LHCP when listening to the downlink" as mentioned.
