“The transmit antennas need to be spatially separated by between 10 and 20
wavelengths and a delay applied to one antenna to achieve effective
de-correlation. The amount of separation and delay depends on the type of
environment to be covered,” says Bard.


Can someone explain this de-correlation to me? Is this not the same as a phase shift? Would there not be a de-correlation when moving from broadside to end fire?

Thanks for any assistance,
John
