It would seem to me that dual polarization would divide the current between the antennas because they are in phase. Circular polarization would allow each antenna to get full power because they are taking turns. Would this assumption be correct?

The dual polarization splits the current between the two radiators. This causes each one to be 3db lower for each than if the same power was going to a single radiator. But by having two radiators, there is more radiator in the air than a single. Two radiators each given same power as one will be 3db stronger. So in effect, splitting power between two radiators would be the same total radiated power as the same power applied to a single radiator. What are everyone's thoughts on this?
