Hi Dave, G1OCN
The polarphaser for 2 meters was also described many years ago in OSCAR-NEWS of AMSAT-UK but unfortunately I don't remember exacly the numbar of the above issue.
In my opinion it is not easy to use a polarphaser because it requires two coax lines coming down from the crossed yagi.
In addition using the actual LEO satellites the rate of change of polarization is very fast during one pass and while operating you have not the time and one more hand to rotate the dial on the front of polarphaser to get the strongest signal.
By the way it was very nice to use the polarphaser in 2 meters downlink with HEO satellites OSCAR-10 and OSCAR-13 because as they were stabilized the rate of change of polarization was very very slow.
I suggest you to save your polarphaser for P3-D

I have an:
"OSCAR Polarphaser PH2/S 2 meters antenna control system" gathering dust. Its the blue box type with SWR meter on the front and N type connectors on the back. Polarity, anti-clockwise, vertical, clockwise and horizontal, is
continuous
via a rotating dial on the front.
The patented design is by GZ HCG, whoever that might be.
Offers please.
