dbi Mismatch Basics

V to V = 0dbi
V to H = -26dbi
i.e. dbi can change from 0 to -26dbi in a 90 degree bank

CP to L (V or H) = -3dbi
Stays -3dbi when the antennae change angles

CP to CP = 0dbi
Stays 0dbi when the antennae change angles

RHCP to LHCP = -26dbi
Stays -26dbi when the antennae change angles

So one should see a marked improvement in multipath rejection and consistancy of video in a turn but not longer range with a CP and L combo.
