Default wi-fi antenna

It is not just a question of squeezing the energy from a sphere into a
hemisphere. If the antenna and its image are separated by a number of
wavelengths nulls occur in the polar plot, so that you cannot simply
claim that a gain of more than 3dB violates the Conservation of
Energy. Principle of Superposition rules. Amen!


Amen!

Alright, you got me. Is that 6 dBi? If so, then I agree. Otherwise I don't
see how. Do you have a reference, example or link showing this 6 dB(dipole)
of gain for two end to end antenna separated by multiple wavelengths.

The principle of superposition states the response of a linear system is the
sum of the elements of the system. If each element is a dipole and both
dipoles are in free space, the output can never be greater than the sum of
the two dipoles acting independently.

Maybe I don't understand what you're saying but I'm definitely missing
something here. Thanks in advance for the help and insight.

Bless you!
