[ANT] Can I just compare the specified gain of different antennas?

Antenna gain is defined as the radiated power in max direction vs the average radiated power. Note that the efficiency of the antenna is also a key parameter as it gives how much the radiated average power is vs the conductive power into antenna. A antenna with high gain is only an advantage when the product orientation can be controlled. If the product orientation is not controller a 0dBi antenna is normally preferred.
