@DrProfer 6dB = x4, 10dB= x10 when comparing against a 1/4wave dipole. If it's against an isotropic you take 2.15dB off the gain figure to give the real performance.
Gain is not on a linear scale. Problem is, why have all that gain when it is cancelled out by a high radiation angle of 35degrees! With WiFi you should be aiming for a very low angle of radiation. A simple antenna with low radiation angle outperforms a high gain high radiation angle aerial every time. Gain isn't everything!

me aythn pou eftiaksa exw apodosh 8db me 10db kai xrisimopoihsa 15kommatia,ama valw 21 kommatia 8a exw apodosh 15 db?????

~3.5 db => 4 elements
~6 db => 8 elements
~9 db => 18 elements
~10 db => 21 elements
