Hi Chris,

They are equivalent in the model for arriving at a field vector that is 
considered with phase and amplitude broken into two distinct parts 
(useful for calculating the combined pattern). It is NOT equivalent in 
how we might wrongly perceive the results!

The problem is users ignore or perhaps do not understand the 
phase relationship, and consider the antenna to have two distinct 
polarizations...which the antenna very clearly does not.

This leads to the VERY false conclusion that tilted polarization is 
somehow magically two distinct separate patterns that are 
somehow more immune to fading.

Like snake-oil.
