You won't see any polarization difference with a yagi on AO-51 because it's downlink is circular polarized. So rotating your linear polarized hand held yagi will make no difference in the downlink signal. This is an ideal situation for hand held operation. :-) Now it will make a difference in our uplink signal.
On SO-50 and AO-27, rotating your yagi to change polarization will make a noticeable change in signal strength.

I just must be the luckiest S.O.B.(*) working AO-51, then...During demonstrations in front of folks, someone in the assemblage almost always asks about polarization. I twist the Arrow, and we all "hear" no difference in its strong, clean signal.
