The purpose of a Wi-Fi antenna is to gather in the signals being transmitted so that a device can access a local network or Internet. Turn an old satellite dish, for example, a Direct TV satellite dish, into a powerful and efficient Wi-Fi antenna.
Yes, you will get more signal strength from a 7 dBI antenna than a 2.2dBI (specifically 4.8 dB). It solves that by radiating energy more directionally than an idea antenna that radiates evenly in all directions (0 dBI). This increased signal strength of 4.8 dB is 10^(4.8/10) = 3 times more power.ighly directional TV antenna and satellite dishes start range often from 16~24 dBi. Gain and beamwidth of peak direction are tradeoffs from isotropic. What this means to you is that when you are on the fringe, they can now aim to get 5dB more which is huge and that gets you into error free mode.
