I’m not sure that’s true unless the AF does some sort of noise cancelling algorithm, which maybe it does. But I don’t see where the antennas alone accomplish that. Yes, +45 would see V at –3dB, but it would also see H at –3dB, and assuming they are uncorrelated, the addition puts you right back where you started.

The antenna does. So those "HV Rockets" on the 45* antenna aren't HV at all.
