This increased signal strength of 4.8 dB is 10^ (4.8/10) = 3 times more power. For example, if you point your base station antenna away from the tower and it has back-lobe radiation, then that energy will be transmitted in the direction of this obstruction. Anyway, the important thing to realize is that a 2.2 dBi antenna could have terrible gain in every direction except for what it is directly pointed at (a narrow beamwidth) and actually be radiating less total power than an omnidirectional antenna.*. It only means that transmitters have to work harder to establish communications with receivers and vice versa. The forward gain is compared with the hypothetical isotropic antenna, which uniformly distributes energy in all directions. 6to23.com is reader-supported. However, no matter how much power is radiated, if a receiver cannot capture and demodulate the radio waves properly, then there will be no communications.
