Hi John, WA4WDL

On the 2.4 GHz from AO-51 the transmitting polarization is
Linear so that in theory for receiving 2.4 GHz RHCP or LHCP
on the ground station don't  make difference.

AO-51 Mode and Antenna Polarization:

T: Linear
V: Linear
U: TX A (usually digital)LHCP
   TX B (usually analog) RHCP
L: Linear
S: Linear
