Neat observation. I was on this morning and worked Luc, VE2DWE and only Luc. I found LHCP to be much much better on the downlink for the entire pass, which is what I expected. I was under the impression the 435.150 antenna was LHCP. The pass this morning was close to directly overhead. Was your pass near the horizon east or west?? Maybe it is a squint angle issue?
P.S. I hope to get on L band again, but my schedule is conspiring against me!

This last pass up the west coast. Very good strong downlink, running a 910 @ 10W to a 16 turn RHCP helix through 40 feet of LMR400. Even good copy running 2 watts! Rx 40 el cp yagi. Early in the pass RHCP was better for rx, later and near LOS LHCP was better. Why? Only station heard was VE7CNA and he was very weak, aside from that I could only talk to myself. I know we have some L banders on the "left" coast and up there in KL7. It's lonely.
