Are you looking at a fixed angle,
or the peak response for each configuration?
If you double the received energy, you gain 3 dB.
It is hard to imagine how doubling the number
of antennas could receive more than double
the energy. Typically stacks produce LESS
than 3 dB peak gain over a single antenna.
