Whether the E-only/H-only explanation is correct or not, the receive 
enhancement is certainly possible on bands limited by external noise. I use 
my tribander for receiving on 160 & 80 and sometimes on 40. The signal 
strength is much less but the signal-to-noise is often much better than on 
either a resonant dipole or vertical.
