No, both EZNEC and elementary physics show that an E-W dipole
sloped 45 degrees radiates exactly equal amounts of both
vertical and horizontal polarization in N and S directions
with zero elevation, in free space.
This is a direct consequence of the fact that a polarization
vector, just like any other vector, can be interpreted as a
sum of two orthogonal vectors with appropriate amplitudes.
Rotation has nothing to do with this.
