Art - What you wrote (and correct me if I misinterpreted) is that me - and others with mere handheld Yagi antennas - are achieving better results on the FM birds than those with more sophisticated linear antennas.

Clint, Rotating a linear polarized Yagi in a circularly polarized field should result in less than a few dB of change, no change if the circular antenna is perfectly circularly polarized. When using a linear antenna ground effects including reflections will cause a larger change. Using circular on both ends will result in less fading from the ground effects and no change in signal for antenna rotation on the S/C side providing the S/C antenna has a good pointing angle. Losses of 22 +dB are reserved for cross polarization of antennas H-V and LH to RH.
